Here is a news article: New England Aquarium The carcass of a very rarely seen, 17-foot, toothed whale with a long slender snout washed up on Jones Beach in Plymouth Friday. 
  
 The carcass of a rare beaked whale washed ashore Friday on Plymouth Long Beach, offering an unusual research opportunity for local marine biologists unaccustomed to sightings of the deep-sea mammal. 
  
 The female whale — 17 feet long, with a long, slender, toothed snout, and weighing almost a ton — is thought to be a Sowerby’s beaked whale, according to the New England Aquarium.

 Beaked whales are “so rarely seen that New England Aquarium biologists have been conferring to determine the exact species,” aquarium officials said in a statement Saturday. The whales are usually found on the continental shelf, hundreds of miles out to sea in the deep ocean, officials said. 
  
 Little is known about the Sowerby’s beaked whale, which are most often seen by commercial fishermen who catch them alongside other sea creatures. New England is believed to be the southern end of the mammal’s range, which extends north into the sub-Arctic, experts said. 
  
 Staff at the aquarium last handled a beaked whale in 2006 in Duxbury, the statement said. 
  
 The purple-hued, dark skinned whale, which resembled a giant dolphin, was such an odd sight that “everybody was kind of scratching their heads,” said Plymouth harbormaster Chad Hunter in a phone interview Saturday. 
  
 Officials received a report for the beached sea mammal at about 10 a.m. Friday, Hunter said. It was stuck on a rocky area of shore during low tide, and “there was no way to get to it and get it out of there,” he said.

 The whale’s weight and inconvenient location meant they needed to wait until about 5 p.m. for high tide to remove the carcass, Hunter said. The harbormaster’s office towed it to the pier and lifted it by crane onto an aquarium trailer. 
  
 Aquarium biologists were performing a necropsy on the whale Saturday afternoon, assisted by staff from the Cape Cod-based International Fund for Animal Welfare. The results were not immediately available. 
  
 It appeared to be fresh, in good condition, and “did not have any obvious entanglement gear or scars or obvious trauma from a vessel strike,” according to the aquarium statement. 
  
 Sowerby’s beaked whales were named after English scientist and watercolor artist John Sowerby, who described one of the species that was stranded in Scotland’s Moray Firth in 1800, according to the nonprofit Whale and Dolphin Conservation. They are not often seen in the wild, but are among the most commonly stranded species of beaked whale, according to the conservation. 
  
 Few organizations have substantial data on beaked whales, though there more than 20 species of them living in the deep ocean, said aquarium spokesman Tony LaCasse. When one surfaces, everyone in the marine biology community pays attention, he said. 
  
 To have a beaked whale specimen offers a chance for “a glancing insight into a marine species that not much is known of,” LaCasse said. ||||| This undated photo provided by the New England Aquarium shows the carcass of rarely-seen deep water beaked whale that washed ashore on Jones Beach in Plymouth, Mass.

 BOSTON (AP) — Biologists with the New England Aquarium are investigating what may have caused a rarely-seen deep water whale to wash up on a Massachusetts beach. 
  
 The carcass of the 17-foot female, weighing almost a ton, was found Friday on Jones Beach in Plymouth. 
  
 Aquarium biologists and staff from the International Fund for Animal Welfare are performing a necrospy at the Woods Hole Oceanographic Institution. They believe the whale is a Sowerby's beaked whale, but the aquarium hasn't handled a beaked whale since 2006. 
  
 Several species of beaked whales are found about 200 miles offshore in the North Atlantic. 
  
 The whales have long, slender snouts and feed in cold, deep water on small fish. Commercial fishermen sometimes net them accidentally. 
  
 The carcass offers a chance for biologists to learn more about them. ||||| Sowerby's Beaked Whale (Mesoplodon bidens)

 Species Description 
  
 Weight: 2,200-2,900 lbs (1,000-1,315 kg) Length: 14.5-21 ft (4.5-5.5 m) Appearance: small to medium-sized charcoal gray body with a very long, slender beak and a bulge on the forehead area Lifespan: unknown, but sexually mature at around 7 years Diet: small fish like Atlantic cod and cephalopods like squid Behavior: they have a low profile at the surface and a small, inconspicuous blow, making them difficult to observe and identify at sea 
  
 Sowerby's beaked whales, sometimes known as the "North Atlantic beaked whale," are little known members of the beaked whale family (Ziphiidae). As adults, Sowerby's beaked whales can reach estimated lengths of 14.5-21 ft (4.4-5.5 m) and weigh 2,200-2,900 lbs (1,000-1,318 kg). Males, which are generally larger, can be distinguished from females and juveniles by a pair of visible teeth that erupt from the slightly arched lower jaw. Females and juveniles have teeth as well, but the teeth remain hidden beneath the gum tissue of the mouth, and their jawline is straight. This species of beaked whale is difficult to observe and identify at sea due to a low profile at the surface and a small, inconspicuous blow. 
  
 Sowerby's beaked whales have a small to medium-sized body with a very long, slender beak relative to other mesoplodonts, as well as a bulge on the forehead area. The beak often emerges at a steep angle when surfacing. They have a small, wide-based, slightly "falcate" "dorsal" fin located far down (about two-thirds) the animal's back. Most of the body has a charcoal gray coloration with a pale underside. The lower jaw is usually light gray or white. Calves are generally darker than adults. This species has less visible scarring than most other beaked whale species. 
  
 Many species of beaked whales (especially those in the genus Mesoplodon) are very difficult to distinguish from one another (even when dead). At sea, they are challenging to observe and identify to the species level due to their cryptic, skittish behavior, a low profile, and a small, inconspicuous blow at the waters surface; therefore, much of the available characterization for beaked whales is to genus level only. Uncertainty regarding species identification of beaked whales often exists because of a lack of easily discernable or distinct physical characteristics. 
  
 Sowerby's whales are usually found individually or in small, closely associated groups averaging between 3-10 individuals. Regular dives range from 10-15 minutes, but dives of at least 28 minutes reaching depths up to 4,920 ft (1,500 m) have been recorded. While diving, they use suction to feed on small fish (e.g., Atlantic cod) and cephalopods (e.g., squid) in deep waters. 
  
 Sowerby's beaked whales may reach sexual maturity at about 7 years of age. Their breeding season may be from late winter to spring. A sexually mature female will give birth to a single newborn calf that is about 8-9 ft (2.4-2.7 m) long and weighs about 375 lbs (170 kg). The estimated lifespan of this species is unknown. 
  
 Habitat 
  
 Sowerby's beaked whales prefer the deep, cold temperate and subarctic waters of the North Atlantic Ocean, but have been reported near the ice pack as well.

 Distribution 
  
 Sowerby's beaked whales are distributed throughout the North Atlantic Ocean (30-71° North), which includes the Norwegian Sea, Labrador Sea, Iceland, Baltic Sea, and south to Massachusetts, Madeira, and the Canaries. Reports of this species in Canadian waters are considered rare. They are not known to occur in the Mediterranean Sea. Strandings have occurred in Florida and Italy, but these are considered outside their normal range. Their distribution may vary depending on the movements of oceanographic currents. There are no known seasonal movements or migrations for this species. 
  
 Population Trends 
  
 For management purposes, Sowerby's beaked whales inhabiting U.S. waters have been placed in the Western North Atlantic stock. No current population estimates are available for this species of beaked whale. The status of the stock is unknown, but is classified as "strategic." This species may be relatively abundant in the North Sea. There are insufficient data to determine the population trends for this species, but they are probably not rare. 
  
 Threats 
  
 bycatch from fishing gear, such as driftnets and gillnets off the U.S. Atlantic coast 
  
 hunting, cetaceans are targeted in Newfoundland and by Norwegian whalers off of Iceland and in the Barents Sea 
  
 underwater sounds and anthropogenic noise anthropogenic noise levels in the world's oceans are an increasing habitat concern, particularly for deep-diving cetaceans like Sowerby's beaked whales that use sound to feed, communicate, and navigate in the ocean 
  
  
  
 Conservation Efforts 
  
 The International Union for Conservation of Nature and Natural Resources (IUCN's) Red List of Threatened Species considers this species "Data Deficient" due to insufficient information on population status and trends. 
  
 Regulatory Overview 
  
 This species is protected under the Marine Mammal Protection Act of 1972, as amended.

 Classification: Sowerby's beaked whale was the first of the beaked whales to be discovered. An individual was stranded in the Moray Firth in 1800, and described four years later by the watercolour artist John Sowerby. While it is not commonly seen in the wild, it is one of the most commonly stranded beaked whales. 
  
 Appearance: From stranded whales a physical description of Sowerby's beaked whales can be made. It has a long, slender beak resembling a dolphin's, and a low melon in front of the blowhole. A pair of teeth erupt midway along the beak in adult males. This feature is distinctive, but is difficult to use as a means of identification as the teeth are only visible at close range. It has a spindle-shaped body and is dark bluish-grey in colour, with a sandy colouration on the head and beak. The underside is lighter, especially in young animals, with grey or white spots. The flippers are long compared to other species in the beaked whale family. The dorsal fin is small and curved with a rounded tip. Their tail flukes are dark on both sides and as with other Mesoplodonts, there is no middle notch. 
  
 Behaviour: Little is known about this beaked whale's behaviour as they are rarely seen at sea. Sowerby's whales have been described as bringing their heads out of the water at a steep angle when surfacing. They have been seen in groups of up to ten individuals, and they have occasionally been seen tail-slapping, breaching and spy-hopping. Dives of between 12 and 28 minutes have been recorded with the whale resurfacing up to 800m away from where they last dived. When stranded they make a sound similar to that of a cow mooing. 
  
 Distribution: Sowerby's beaked whales have one of the most northerly distributions of all the beaked whales. They are found in the eastern North Atlantic, in the seas around Norway, the UK and Iceland, and in the western North Atlantic off of Canada and Massachusetts, USA. As with other species of beaked whales, Sowerby's beaked whales prefer deeper waters and are found offshore past the continental shelf. Threats to the species may include incidental whaling, accidental entanglement in fishing gear, climate change, marine debris, and noise pollution and whilst the worldwide population is unknown the IUCN list the species as Data Deficient. |||||
A summary of this is?
– How rare is the carcass of a beaked whale that washed ashore in Massachusetts on Friday morning? This rare: "New England Aquarium biologists have been conferring to determine the exact species," officials with the aquarium said in a statement released Saturday, per the Boston Globe. The 17-foot-long female that ended up on a beach in Plymouth is thought to be a Sowerby's beaked whale, a species that the nonprofit Whale and Dolphin Conservation reports is seen only infrequently in the wild but is "one of the most commonly stranded beaked whales." The aquarium last handled a beaked whale in 2006, reports the AP. Per NOAA Fisheries, "At sea, [Sowerby's beaked whales] are challenging to observe and identify to the species level due to their cryptic, skittish behavior, a low profile, and a small, inconspicuous blow at the (water's) surface." And when it comes to being "at sea," the Globe reports the whales are typically found hundreds of miles from the coast on the continental shelf, where commercial fisherman occasionally reel one in. A necropsy is being performed; the aquarium notes the nearly one-ton female "did not have any obvious entanglement gear or scars or obvious trauma from a vessel strike." (This beaked whale may be the deepest-diving mammal on the planet.)
Här är en nyhetsartikel: New England Aquarium Slaktkroppen av en mycket sällan sedd, 17-fot, tandad val med en lång smal nos spolas upp på Jones Beach i Plymouth fredag. Slaktkroppen av en sällsynt näbbval spolades i land fredag på Plymouth Long Beach, vilket erbjuder en ovanlig forskning möjlighet för lokala marinbiologer ovana vid observationer av djuphavsdäggdjur. Honvalen — 17 fot lång, med en lång, slank, tandad nos och som väger nästan ett ton — tros vara en Sowerbys näbbval, enligt New England Aquarium. Annons Beaked valar är “så sällan sett att New England Aquarium biologer har gett för att bestämma den exakta arten,” akvarium tjänstemän sade i ett uttalande lördag. Valarna hittas vanligen på kontinentalsockeln, hundratals kilometer ut till havs i det djupa havet, sade myndigheterna. Litet är känt om Sowerbyns näbbval, som oftast ses av kommersiella fiskare som fångar dem vid sidan av andra havsdjur. New England tros vara den södra änden av däggdjurets utbredningsområde, som sträcker sig norrut in i det subarktiska, menade experter. Personalen på akvariet hanterade senast en näbbad val 2006 i Duxbury, sade uttalandet. Den lila hydda, mörkhyade valen, som liknade en jättedelfin, var en så udda syn att "alla liksom kliade sig i huvudet", sade Plymouth hamnkapten Chad Hunter i en telefonintervju lördag. Tjänstemännen fick en rapport för det strandade havsdäggdjuret omkring klockan 10 på fredagen, sade Hunter. Den fastnade på ett stenigt område av stranden under lågvatten, och “det fanns inget sätt att komma till den och få ut den därifrån”, sade han. Annons Valens vikt och obekväma läge innebar att de behövde vänta till omkring klockan 17 på högvatten för att avlägsna kadavret, sade Hunter. Hamnkaptenens kontor bogserade den till piren och lyfte den med kran på en akvariesläpvagn. Akvariumbiologer utförde en obduktion på valen lördag eftermiddag, assisterad av personal från Cape Cod-baserade internationella fonden för djurskydd. Resultaten var inte omedelbart tillgängliga. Det verkade vara färskt, i gott skick, och “inte hade någon uppenbar snärjning redskap eller ärr eller uppenbara trauma från ett fartyg strejk,” enligt akvariet uttalande. Sowerbys näbbvalar fick sitt namn efter den engelske vetenskapsmannen och akvarellkonstnären John Sowerby, som beskrev en av de arter som strandade i Skottlands Moray Firth år 1800, enligt den ideella Valen och Dolphin Conservation. De ses inte ofta i vilt tillstånd, men hör enligt konserveringen till de oftast strandade arterna av näbbval. Få organisationer har omfattande data om näbbvalar, även om det finns mer än 20 arter av dem som lever i det djupa havet, sade akvarie talesman Tony LaCasse. När man går upp på ytan är alla inom marinbiologin uppmärksamma, sade han. Att ha en näbbad val specimen erbjuder en chans för “en glancing inblick i en marin art som inte mycket är känt om,” LaCasse sade.

Som vuxna kan Sowerbys näbbvalar nå uppskattade längder på 14,5-21 ft (4,4–5,5 m) och väga 2 200–2 900 lbs (1 000–1,318 kg). Hannar, som i allmänhet är större, kan skiljas från honor och juveniler genom ett par synliga tänder som får utbrott från den lätt välvda underkäken. Honor och juveniler har också tänder, men tänderna förblir gömda under tandköttsvävnaden i munnen, och deras käklinje är rak. Denna art av näbbval är svår att observera och identifiera till havs på grund av en låg profil vid ytan och ett litet, oansenligt slag. Sowerbys näbbvalar har en liten till medelstor kropp med en mycket lång, slank näbb i förhållande till andra mesoplodonter, samt en utbuktning på pannområdet. Näbben framträder ofta i brant vinkel när den dyker upp. De har en liten, bred bas, något "falsk" "dorsalfena" som ligger långt ner (cirka två tredjedelar) djurets rygg. Större delen av kroppen har en kolgrå färgsättning med en blek undersida. Underkäken är vanligen ljusgrå eller vit. Kalvar är generellt mörkare än vuxna. Denna art har mindre synlig ärrbildning än de flesta andra näbbsvalarter. Många arter av näbbvalar (särskilt de i släktet Mesoplodon) är mycket svåra att skilja från varandra (även när de är döda). Till havs är de utmanande att observera och identifiera till artnivån på grund av sitt kryptiska, skettiska beteende, en låg profil, och ett litet, oansenligt slag vid vattenytan; därför är mycket av den tillgängliga karakteriseringen för näbbvalar endast till släktesnivå. Osäkerhet beträffande artidentifikation av näbbvalar förekommer ofta på grund av brist på lätt urskiljbara eller distinkta fysiska egenskaper. Sowerbys valar hittas vanligen var för sig eller i små, nära associerade grupper som i genomsnitt ligger mellan 3-10 individer. Regelbundna dyk sträcker sig från 10-15 minuter, men dyk på minst 28 minuter som når djup upp till 4.920 ft (1500 m) har registrerats. Vid dykning använder de sug för att livnära sig på småfisk (t.ex. atlanttorsk) och bläckfisk (t.ex. bläckfisk) i djupa vatten. Sowerbys näbbvalar kan nå könsmognad vid cirka 7 års ålder. Deras häckningssäsong kan vara från senvinter till vår. En könsmogen hona ska föda en enda nyfödd kalv som är cirka 8-9 ft (2,4-2,7 m) lång och väger cirka 375 lbs (170 kg). Den uppskattade livslängden för denna art är okänd. Habitat Sowerbys näbbvalar föredrar de djupa, kalla tempererade och subarktiska vattnen i Nordatlanten, men har rapporterats nära ispacken också. Sowerby's Beaked Whale Range Map (klicka för större bild PDF) Distribution Sowerby's näbbvalar distribueras över hela Nordatlanten (30-71° Nord), som inkluderar Norska havet, Labradorhavet, Island, Östersjön, och söderut till Massachusetts, Madeira, och Kanarieöarna. Rapporter om denna art i kanadensiska vatten anses sällsynta. De är inte kända för att förekomma i Medelhavet. Strandningar har förekommit i Florida och Italien, men dessa anses ligga utanför deras normala utbredningsområde. Deras utbredning kan variera beroende på oceanografiska strömmars rörelser. Det finns inga kända säsongsbundna rörelser eller flyttningar för denna art. Populationstrender I förvaltningssyfte har Sowerbys näbbvalar som bebor amerikanska vatten placerats i det västnordostlantiska beståndet. Inga aktuella populationsuppskattningar finns tillgängliga för denna art av näbbval. Beståndets status är okänd, men klassas som "strategisk". Denna art kan vara relativt riklig i Nordsjön. Det finns inte tillräckligt med data för att fastställa populationstrender för denna art, men de är troligen inte sällsynta. Hot om bifångster från fiskeredskap, såsom drivgarn och nät utanför den amerikanska atlantkusten, valar är måltavlor i Newfoundland och av norska valfångare utanför Island och i Barents hav undervattensljud och antropogena bullerantropogena bullernivåer i världens hav är en ökande livsmiljöfråga, särskilt för djupdykande valar som Sowerbys näbbvalar som använder ljud för att mata, kommunicera och navigera i oceanen Bevarande insatser Internationella naturvårdsunionen (IUCN:s) rödlista över hotade arter anser denna art "Databristig" på grund av otillräcklig information om populationsstatus och trender.

Here is a news article: New England Aquarium The carcass of a very rarely seen, 17-foot, toothed whale with a long narrow nose washed up on Jones Beach in Plymouth Friday. The carcass of a rare beak whale was washed ashore Friday at Plymouth Long Beach, offering an unusual research opportunity for local marine biologists unaccustomed to sightings of deep-sea mammals. The female whale — 17 feet tall, with a long, slender, toothed snout and weighing nearly a ton — is believed to be a Sowerby beak whale, according to the New England Aquarium. Advertisement Beaked whales are “so rarely seen that New England Aquarium biologists have given to determine the exact species,” aquarium officials said in a statement Saturday. The whales are usually found on the continental shelf, hundreds of miles out to sea in the deep sea, authorities said. Little is known about Sowerbyn's beak whale, which is usually seen by commercial fishermen who catch them alongside other sea animals. New England is believed to be the southern end of the mammal range, extending northward into the subarctic, experts argued. The staff at the aquarium last handled a beaked election in 2006 in Duxbury, the statement said. The purple hut, dark-skinned whale, which resembled a giant dolphin, was such an odd sight that "everyone kind of scratched his head," said Plymouth harbor captain Chad Hunter in a telephone interview Saturday. The officials received a report for the stranded sea mammal at about 10 a.m. on Friday, Hunter said. It got stuck in a rocky area of the beach under low tide, and “there was no way to get to it and get it out of there,” he said. Advertisement The weight and uncomfortable location of the whale meant they had to wait until about 5 p.m. on high tide to remove the carcass, Hunter said. The harbor captain's office towed it to the pier and lifted it with a crane on an aquarium trailer. Aquarium biologists performed an autopsy on the Saturday afternoon elections, assisted by personnel from the Cape Cod-based International Fund for Animal Welfare. The results were not immediately available. It appeared to be fresh, in good condition, and “did not have any obvious entrapment gear or scars or obvious trauma from a ship strike,” according to the aquarium statement. Sowerby's beak whales were named after English scientist and watercolour artist John Sowerby, who described one of the species that beached in Scotland's Moray Firth in 1800, according to the nonprofit Election and Dolphin Conservation. They are not often seen in the wild, but, according to the preservation, belong to the most frequently stranded species of beak whale. Few organizations have extensive data on beak whales, although there are more than 20 species of those living in the deep sea, aquarium spokesman Tony LaCasse said. When you go up on the surface, everyone in marine biology is paying attention, he said. Having a beaked whale specimen offers a chance for “a glancing insight into a marine species that is not much known about,” LaCasse said.

(Associated Press) BOSTON (AP) — Biologists with New England Aquarium are investigating what may have caused an infrequently beheld deep water whale to wash up on a Massachusetts beach. The carcass of the female, weighing nearly a ton, was found Friday at Jones Beach in Plymouth. Aquarium biologists and personnel from the International Fund for Animal Welfare perform a necrospy at the Woods Hole Oceanographic Institution. They think the whale is a Sowerby beak whale, but the aquarium has not handled a beak whale since 2006. Several species of beak whales are located about 200 miles off the coast of the North Atlantic. The whales have long, slender noses and feed in cold, deep water on small fish. Commercial fishermen sometimes accidentally catch them. Cadavret gives biologists a chance to learn more about them. eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri ry eri eri eri eri eri eri eri ry eri eri eri eri eri eri ry eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri eri . · Sowerby's beak whale was the first living species of beak whale discovered. · Sowerby's beak whale's scientific species name (bidens) derives from the Latin word bee for "two" and it's for "tea". Status MMPA - Sowerby's beak whales, like all marine mammals, are protected under the MMPA. CITES Appendix II - throughout its range Taxonomy Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetacea Family: Ziphiidae Genus: Mesoplodon Species: bidens Species Description Weight: 2,200-2,900 lbs (1,000-1,315 kg) Length: 14.5-21 ft (4.5-5.5 m) Appearance: small to medium-sized coal-grey body with a very long, narrow beak and a bulge in the forehead area Life span: unknown, but sexmature at about 7 years Diet: small fish such as Atlantic cod and octopus Behavior: they have a low profile at the surface and a small, unsound blow, making them difficult to observe and identify at the sea Sowerby's beaked whales, sometimes known as the "North Atlantic beak whale", are little known members of the family beak whales (Ziphiidae). As adults, Sowerby's beak whales can reach estimated lengths of 14.5-21 ft (4.4–5.5 m) and weigh 2,200–2,900 lbs (1,000–1.318 kg). Males, generally larger, can be distinguished from females and juveniles by a pair of visible teeth erupting from the slightly arched lower jaw. Females and juveniles also have teeth, but the teeth remain hidden under the gum tissue of the mouth, and their jaw line is straight. This species of beak whale is difficult to observe and identify at sea due to a low profile at the surface and a small, inconspicuous blow. Sowerby's beak whales have a small to medium-sized body with a very long, slender beak relative to other mesoplodonts, as well as a bulge on the boiler area. The beak often appears at a steep angle when it appears. They have a small, broad base, slightly "false" "dorsal fin" located far down (about two thirds) the animal's back. Most of the body has a carbon grey coloration with a pale underside. The lower jaw is usually light grey or white. Calves are generally darker than adults. This species has less visible scarring than most other beak whale species. Many species of beak whales (especially those in the genus Mesoplodon) are very difficult to distinguish from each other (even when dead). At sea, they are challenging to observe and identify to the species level due to their cryptic, skittic behavior, a low profile, and a small, inconspicuous blow at the surface of the water; therefore, much of the available characterization for beak whales is only to genus level. Uncertainty regarding species identification of beak whales often occurs due to a lack of readily discernible or distinct physical properties. Sowerby's whales are usually found separately or in small, closely associated groups that average between 3-10 individuals. Regular dives range from 10-15 minutes, but dives of at least 28 minutes reaching depths up to 4,920 ft (1500 m) have been recorded. When diving, they use suction to feed on small fish (e.g. Atlantic cod) and squid (e.g. squid) in deep waters. Sowerby's beak whales can reach sexual maturity at approximately 7 years of age. Their breeding season could be from late winter to spring. A sex mature female should give birth to a single newborn calf about 8-9 ft (2.4-2.7 m) long and weigh about 375 lbs (170 kg). The estimated life span of this species is unknown. Habitat Sowerby's beak whales prefer the deep, cold temperate and subarctic waters of the North Atlantic, but have been reported near the ice pack as well. Sowerby's Beated Whale Range Map (click for larger image PDF) Distribution Sowerby's beak whales are distributed throughout the North Atlantic (30-71° North), which includes the Norwegian Sea, the Labrador Sea, Iceland, the Baltic Sea, and south to Massachusetts, Madeira, and the Canary Islands. Reports of this species in Canadian waters are considered rare. They are not known to occur in the Mediterranean. Beachings have occurred in Florida and Italy, but these are considered to be outside their normal range. Their distribution may vary depending on the movements of oceanographic currents. There are no known seasonal movements or migrations for this species. Population trends For management purposes, Sowerby's beak whales inhabiting U.S. waters have been placed in the West Nordo-Tlantic stock. No current population estimates are available for this species of beak whale. The status of the stock is unknown, but is classified as "strategic". This species can be relatively abundant in the North Sea. There are not enough data to determine population trends for this species, but they are probably not rare. Threats of by-catch from fishing gear, such as drift nets and nets off the American Atlantic coast, whales are targeted in Newfoundland and by Norwegian whalers off Iceland and in the Barents Sea underwater sounds and anthropogenic noise anthropogenic noise levels in the world's oceans are an increasing habitat issue, especially for deep-diving whales such as Sowerby's beak whales using sounds to feed, communicate and navigate in the ocean Conservation efforts International Union of Conservation of Nature (IUCN) Red List of Threatened Species considers this species "Data deficient" due to insufficient information on population status and trends.

An individual stranded in Moray Firth in 1800, and was described four years later by watercolour artist John Sowerby. Although not commonly found in the wild, it is one of the most common stranded beak whales. Appearance: From stranded whales, a physical description of Sowerby's beak whales can be made. It has a long, narrow beak similar to a dolphin, and a low melon in front of the blowhole. A pair of teeth erupt midway along the beak in adult males. This characteristic is distinctive, but is difficult to use as an identifier as teeth are only visible at close range. It has a spider-shaped body and is dark blue grey in color, with a sandy coloration on the head and beak. The underside is lighter, especially in young animals, with grey or white spots. The fans are long compared to other species in the beak whale family. The dorsal fin is small and bent with a rounded tip. Their tail tabs are dark on both sides and as with other mesoplodonts, there is no middle noch. Behavior: Little is known about the behavior of this beak whale as they are rarely seen at sea. Sowerby's whales have been described as bringing their head out of the water at a steep angle as they appear. They have been seen in groups of up to ten individuals, and they have occasionally been seen tail flapping, breaking in and spying. Divings of between 12 and 28 minutes have been recorded with the whales awakening up to 800 meters away from where they last appeared. When they're stranded, they make a noise similar to that of a cow like mooar. Distribution: Sowerby's beak whales have one of the northernmost ranges of all beak whales. They are found in the eastern North Atlantic, in the seas around Norway, the United Kingdom and Iceland as well as in the western North Atlantic off Canada and Massachusetts, United States. As with other species of beak whales, Sowerby beak whales prefer deeper waters and are found offshore past the continental shelf. The threats to the species may be accidental whaling, accidental entanglements in fishing gear, climate change, marine debris and noise pollution and while the global population is unknown, the IUCN lists the species as Data Deficicient.

– Hur ovanligt är det med en näbbval som spolades i land i Massachusetts på fredag morgon? Detta sällsynta: "New England Aquarium biologer har gett för att bestämma den exakta arten," tjänstemän med akvariet sade i ett uttalande som släpptes lördag, per Boston Globe. Den 17 fot långa honan som hamnade på en strand i Plymouth tros vara en Sowerbys näbbval, en art som de ideella Whale and Dolphin Conservation rapporterar ses endast sällan i vilt tillstånd men är "en av de vanligaste strandade näbbvalarna." Akvariet hanterade senast en näbbad val 2006, uppger AP. Per NOAA Fisheries, "Till havs är [Sowerbys näbbvalar] utmanande att observera och identifiera till artnivån på grund av sitt kryptiska, skettiska beteende, en låg profil, och ett litet, oansenligt slag vid (vattnets) yta." Och när det gäller att vara "till sjöss", rapporterar Globe att valen vanligtvis hittas hundratals kilometer från kusten på kontinentalsockeln, där kommersiella fiskare ibland rullar in en. En obduktion utförs; akvariet noterar att nästan en tons hona "inte hade någon uppenbar snärjning redskap eller ärr eller uppenbara trauma från ett kärl strejk." (Denna näbbval kan vara planetens djupaste däggdjur.)
– How unusual is it with a beak whale washed ashore in Massachusetts on Friday morning? This rare: "New England Aquarium biologists have given to determine the exact species," officials with the aquarium said in a statement released Saturday, per the Boston Globe. The 17-foot-long female who ended up on a beach in Plymouth is believed to be a Sowerby beak whale, a species reported by the nonprofit Whale and Dolphin Conservation is only rarely seen in the wild but is "one of the most common stranded beak whales." The aquarium last handled a beaked election in 2006, states AP. Per NOAA Fisheries, "At sea, [Sowerby's beak whales] are challenging to observe and identify to the species level due to their cryptic, skittish behavior, a low profile, and a small, inconspicuous blow at the (water's) surface." And when it comes to being "at sea," Globe reports that the whale is usually found hundreds of miles from the coast of the continental shelf, where commercial fishermen sometimes roll one in. An autopsy is performed; the aquarium notes that almost a ton of female "had no apparent entrapment gear or scars or obvious trauma from a vessel strike." (This beak whale may be the planet's deepest mammal.)
