the study discusses distribution and taxonomic problems of the milnesium species known from south america . as of now , nine milnesium taxa are known from this region ( including two new species reported in this paper ) . additionally , the study broadens our knowledge of tardigrades ' feeding behaviour , provides some details about their diet and suggests that the type of prey chosen by some species belonging to the family milnesiidae may be associated with the width of their buccal tube .

milnesium argentinum and m . beatae are new taxa for science . as of now , nine milnesium taxa are known from south america ( including the two new species and two newly recorded taxa for argentina , reported in this paper ) . the presence of m . tardigradum s . s . in south america needs confirmation and for now it should be considered as dubious . it is probable that width of buccal tube may limit a prey size and play an important role in the feeding behaviour in the family milnesiidae . studies on the feeding behaviour in tardigrades are in initial phase and definitive conclusions are not possible at this moment .

claws of the milnesium type , slender . primary branches on all legs with small accessory points on the top of the branch . secondary claws of all legs with rounded basal thickenings ( lunules ) ( sometimes barely visible ) . claw configuration : [ 2 - 3 ] - [ 2 - 2 ] . single , long transverse , cuticular bars under claws i–iii present .

the diversity and distribution of the tardigrades in south america are rather poor and selective , as is information about their feeding behaviour and diet . to date , only ca . 210 tardigrade taxa have been reported from the region of south america . in the present paper , we provide an update of the distribution of the genus milnesium in south america and discuss some aspects of the feeding behaviour in the family milnesiidae .

besides the abovementioned the most similar species , m . beatae sp . nov . is similar to other species of the genus milnesium with the claw configuration [ 3 - 3 ] - [ 3 - 3 ] ( m . alabamae , m . antarcticum , m . asiaticum , m . barbadosense , m . eurystomum , m . granulatum , m . longiungue and m . zsalakoae ) or with a sculptured cuticle ( m . beasleyi , m . katarzynae , m . krzysztofi and m . reticulatum ) .

characteristics and measurements of the species used in the differential diagnosis are given according to the original descriptions ( ramazzotti 1962 ; pilato et al . 2002 ; kaczmarek et al . 2004 ; tumanov 2006 ; kaczmarek and michalczyk 2007 ; wallendorf and miller 2009 ; kaczmarek et al . 2012a ; meyer et al . 2013 ) or are based on direct examination of type material ( holotype and paratypes of milnesium beasleyi kaczmarek et al . 2012a ) . ramazzottius specimens were verified and identified using the key to the world tardigrada ( ramazzotti and maucci 1983 ) , a more modern key to the genus ramazzottius ( biserov 1998 ) , and remarks discussed by pilato et al . ( 2013 ) .

cuticle cuticle covered with numerous tiny , shallow and rounded depressions ( pseudopores ) . under pcm pseudopores are visible as light spots with blurry edges . two cephalic papillae positioned laterally .

six peribuccal papillae ( ventral papilla smallest ) and six peribuccal lamellae ( of equal size ) around the mouth opening . buccal tube funnel - shaped , wider anteriorly ( on average the posterior diameter is 73 % of the anterior diameter ) . pharyngeal bulb elongated , pear - shaped and without placoids or septulum .

in a lichen sample collected by the first author in bârlad town in july , 2013 , 53 individuals and two exuvia ( with 16 eggs ) of the new species were found . additionally , 55 specimens of ramazzottius oberhaeuseri ( doyère , 1840 ) were found in the same sample , including 9 specimens in simplex stage and 9 eggs .

all specimens were extracted according to dastych ( 1980 , 1985 ) and mounted on microscope slides in hoyer’s medium . observations , measurements and photomicrographs were taken using phase contrast microscopy ( pcm ) ( olympus bx41 with digital camera artcam - 300mi ) . all measurements ( determined with quickphoto camera 2 . 3 ) are given in micrometers [ μm ] .

body length was measured from the mouth to the end of the body excluding the hind legs . the buccal tube and claws characteristics were measured according to tumanov ( 2006 ) and michalczyk et al . ( 2012a ) . subsequently , claw configuration is described according to michalczyk et al . ( 2012a , 2012b ) . other morphometric data were calculated using the pt ratio : the ratio of the length of a given structure to the length of the buccal tube , expressed as a percentage ( pilato 1981 ) . the pt values are always provided in italics in order to differentiate them from length values .

holotype ( female ) , 52 paratypes and 2 exuvia with 7 and 9 smooth eggs .

body brownish ( in live specimens ) or transparent ( in fixed specimens ) with eyes ( visible before and after mounting in hoyer’s medium - 90 % of fixed specimens had eyes ) . six peribuccal papillae ( ventral papilla smallest ) and six peribuccal lamellae ( of equal size ) around the mouth opening present . two cephalic papillae positioned laterally . the cuticle is covered with numerous tiny , shallow and rounded depressions ( pseudopores ) (

, is located mostly in the southern hemisphere , with a relatively small portion ( ca . 10 % ) in the northern hemisphere . it includes 12 sovereign countries . geographically , the western part of south america is dominated by the andes while the eastern part contains both highland regions and large river basins such as the amazon , paraná and orinoco . most of the continent lies in the tropics and the entire south american territory belongs to neotropical ecozone ( peel et al .

argentina , located in southern part of the continent , shares land borders with chile across the andes to the west , bolivia and paraguay to the north , brazil to the northeast , uruguay and the south atlantic ocean to the east and the drake passage to the south . argentina is the eighth largest country in the world and the second largest in latin america . it is subdivided into 23 provinces and one autonomous city - buenos aires . the exceptionally diverse climate depends on the geographic regional division and ranges from tropical in the north to subpolar in the far continental south ( edwards

río negro , one of the 23 provinces of argentina , is located at the northern edge of patagonia . the central region of the province is dominated by a series of plateaus and isolated hills with altitude ranging from 600 to 1 , 000 m asl . towards the west , the foothills of the andes are dominated by a series of low valleys . the climate of the province is temperate at low elevations and very harsh in the highest andean peaks ( edwards

, but this hypothesis needs to be confirmed . we strongly suggest that all specimens reported as

s . s . from this region should be re - examined and determined based on the modern taxonomic characters ( see also michalczyk et al .

) . this species is characterized by a very wide and relatively short buccal tube , claw configuration [ 3 - 3 ] - [ 3 - 3 ] and smooth cuticle . recently , a similar species ( with a short and wide buccal tube ) ,

, was described from north america ( usa , north carolina and tennessee ) ( bartels et al .

) . in this situation , we suggest that the examples , especially from south and north america , should be re - examined ( see also michalczyk et al .

localities and number of specimens in present studies : two females in sample ii .

) , such wide and discontinuous geographic distribution can suggest a complex of cryptic species , but testing this hypothesis requires molecular data which are not yet available . we suggest that at least the examples from europe should be carefully re - examined ( see also michalczyk et al .

) . this unique subspecies is characterized by the presence of short spines on dorsal cuticle . it should be probably promoted to the species level , but the re - description based on type material ( or based on specimens collected in the type locality ) is necessary ( michalczyk et al .

species have been recorded from many localities throughout the world ( michalczyk et al .

was the only recognised species in the genus and it has been considered as an extremely cosmopolitan taxon ( e . g . ramazzotti and maucci

) and finally excluded from the list of tardigrade taxa at all . it was not until 1990 that binda and pilato described a new

, from tierra del fuego . later , new species were described only occasionally mainly due to the lack of a clear diagnosis of the nominal species

and described five new species . since this time , many new species have been described and now 25 taxa ( including the two new species described in this paper ) are known in the genus ( degma et al .

) . the majority of the newly described species are known only from their type localities and michalczyk et al . (

have truly restricted geographic ranges , as was also shown in other tardigrade genera ( e . g . pilato and binda

s . l . has a wide distribution in south america , however the presence of this species in this region is doubtful and needs confirmation . the present study seems to confirm this hypothesis , because although four

have rather a narrower geographic range ( restricted to holarctic or palearctic ) , although more extensive studies ( molecular ) are necessary in other regions of south america .

) , which can suggest the presence of cryptic species complexes or a specific distribution of some of the taxa ( e . g . pantropical for

) . in this situation , only detailed morphological and molecular studies could shed light on this issue .

very little is known about food preferences in tardigrades , although , many different types of food sources have been reported , i . e . plant cell fluids , algae , bacteria , protozoa and small invertebrates like nematodes , rotifers and other tardigrades ( for the review , see schill et al .

) . previous studies have focused on the following : a ) the rate of consumption , e . g . in the carnivorous

, e ) life histories of some species and f ) different aspects of tardigrade histology ( e . g . suzuki

are relatively large ( occasionally more than 2 mm but most often between 0 . 5 to 1 . 0 mm ) and inhabit mainly limno - terrestrial habitats ( guil

) . their buccal tube is wide , relatively short , connected with a large pharynx without placoids and associated with large buccal lamellae on a wide mouth ring , which is in agreement with the definition of the ‘carnivore type’ of buccal apparatus proposed by guidetti et al . (

species are considered carnivorous and feed on other small invertebrates like rotifers , nematodes , tardigrades and sometimes also on amoebas ( e . g . kinchin

species suck the entire prey into the gut rather than only single cells or body fluids ( mcinnes et al .

has the ability to properly orient their prey , so that the amoeba can be extracted by the sucking action and later the empty shell can be expelled . however , specific differences in the feeding behaviour in connection with the structure of buccal apparatus in different

( 7 specimens ) were studied . both species were found in the same region of nahuel huapi national park ( río negro province , argentina ) in a few moss samples . five specimens ( two specimens of

sp . nov . ) were found with the remnants of food ( rotifer mastaxes and tardigrade buccal apparatuses and claws ) in their guts . both species were found in the moss samples ( sometimes also together in the same piece of moss ) that also contained rotifers , nematodes and other tardigrades (

species were able to choose from the same type of prey , because the prey were similar in every sample .

are larger ( 360 to 650 μm ) and more bulky ( a wider buccal tube is probably necessary to swallow them ) than typical rotifers which are shorter ( 100 to 500 μm ) and more slender ( a narrower buccal tube is sufficient to swallow them ) . although the numbers are small , these data suggest that the buccal tube width may affect the type of prey consumed . however , it should be also noted that mcinnes et al . (

thulin 1928 ) , which is in agreement with the observations made in the present research .

) observations nor the present research provided a definitive answer whether the buccal tube width has a crucial role in the choice of different types of prey , these studies are the basis for further , more comprehensive studies .

) . however , we know almost nothing about feeding behaviour and prey choice of the members of these monophyletic genera . only claxton (

that had remnants of rotifers in their guts . this is a very interesting observation , because this species has a very long and narrow buccal tube , similarly to the ‘rotifer - feeding’

based on the available data , it can be initially hypothesised that the species from the family milnesiidae with long and narrow buccal tubes ( e . g .

) in contrast to the species with relatively short and wide buccal tubes ( e . g .

or testate amoebae ) . certainly , such conclusions based only on the ‘post - mortem’ studied specimens give us only very limited knowledge on the food that had been eaten just before death ( preservation ) of the animal . such information needs confirmation in further , more detailed experimental studies with molecular methods ( e . g . schill et al .

) or based directly on the observations in cultured animals ( e . g . suzuki

the japanese flying squid , japanese common squid or pacific flying squid , scientific name todarodes pacificus , is a squid of the family ommastrephidae .

this animal lives in the northern pacific ocean , in the area surrounding japan , along the entire coast of china up to russia , then spreading across the bering strait east towards the southern coast of alaska and canada .

they tend to cluster around the central region of vietnam .

how does the japanese flying squid catch air ? it releases a high - pressured water jet for propulsion , and then spreads its fins like wings to glide above the water , according to a new study from marine biologists at hokkaido university .

the main food source of the japanese flying squid is a variety of small fish . they will also consume other types of squid that are out there if food sources are short . fishermen have learned to check their nets often too . otherwise they will discover their catch is far less because larger squid have consumed the smaller ones in there with them .

in japanese waters , squids are mainly caught in summer - autumn squid fishery ; coastal catches are landed fresh while catches from offshore waters are landed as frozen blocks . in addition to squid jigging and net fishing in japanese waters they are also caught in multi - gear fisheries within chinese and korean waters .

the japanese flying squid isn’t as well known as many others out there . they also have features that are distinct to this particular species . you will notice rings around the back of the head . these are used to determine how old they are . they are very small and light weight squid as well .

he added that as the squid are vulnerable when flying , it ' s possible they may be a source of food for sea birds or other predators .

there are no specific management plans in place in chinese waters , but the stock is well managed within japanese limits through tac quotas ; but score 2 and score 4 have been equal to or above 6 in recent years in japanese waters .

the behavior of the japanese flying squid is hard to identify . we don’t know much about them in their natural habitat . at the same time though we can’t learn much from them in captivity . this is one species of squid that tends to not do well at all in such an environment . they suffer from stress so they don’t eat or at like they normally would .

to help conserve the levels of japanese flying squid out there , plenty of effort is put into the process of capturing them . since these squid are going to die anyway after they mate , that is the best time to capture them . the goal is to allow them to successfully mate and for the females to deposit the eggs . then they can be captured before the inevitable death the face occur . this way they aren’t taking away from the life span of these squid in their natural environment .

the fishing season is all year around . however , the most popular seasons are from january to march , and then june to september as this is when the largest catch of japanese flying squid can be caught . they are caught with hook and line , lift nets , and gill nets . the most popular fishing method is hook and line , which is used in jigging .

jun yamamoto and his team had been sailing around the northwest pacific ocean , 600km off the coast of japan , looking for schools of squid . they spotted about 100 20cm squid swimming just below the surface of the ocean , but as they approached around 20 of the squid launched themselves into the air , gliding around 30m in ten seconds . that the squid took flight as the researchers ' boat approached has led yamamoto to speculate that flying is a safety mechanism , to help them espace predators .

they tend to live in the upper layers of the ocean , but are only short lived as they live for only 1 year . within this year of life , the japanese flying squid matures from larvae form . they then fed , grow , migrate , and then at the end of their lives , they congregate in mating grounds where they reproduce . when they reproduce , they die .

the japanese flying squid isn’t unique in either its locomotion or its sperm delivery system . what sets it apart from other squid is its popularity as food , especially in japan , korea and other east asian nations . often it is sold in a processed , dried form ( i . e . , no insemination risk ) , but it is increasingly also consumed raw and sometimes with its internal organs still intact , and thus the species occasionally finds its way into food horror headlines .

it is important to understand the physical process that determines the vertical distribution of egg masses to predict their horizontal drift in relation to embryo survival and subsequent recruitment [ 33 ] . in our previous cycle of experiments [ 13 ] , we observed the spawning behavior of the japanese flying squid and how the thermocline helps to sustain the egg masses in the water column . the present study was designed to investigate the structure and durability of the egg masses , including how they function to prevent infestation , the physical properties , and the role of jelly during embryo development in the egg mass . the fate of the egg mass jelly during and after embryo development was also assessed . the properties of the egg masses observed in vitro were related to seawater parameters in the natural spawning grounds of the japanese flying squid .

dietary studies of squid are difficult because their oesophagus is very narrow as it passes through their brain , therefore food particles must be chewed up very finely and are hard to identify . both dietary analysis and squid fatty acid analysis are being used to determine squid prey species .

when japanese flying squid hook up , the male clutches the female and uses his “hectocotylus” ( the fourth right arm , designed for this sort of hand off ) to grab some spermatophores and stick them onto the lucky lady . it’s the ejaculation device contained in the spermatophores – not the live male squid – that ultimately sends the sperm mass burrowing through the female’s skin . it’s not a powerful enough mechanism to penetrate the thick skin of , say , a human hand . the delicate mucosa inside the human mouth , however , is no problem .

this is the first reported instance of accidental culinary insemination involving a partially cooked squid . in all other cases , unsuspecting diners bit into fully raw squid . but even the raw squid incidents were few and far between . most squid – raw or cooked – is served sans internal organs and is thus unlikely to contain spermatophores . and calamari’s biggest threat to health is probably the whole breading and frying thing .

high amounts of japanese flying squid are consumed in both japan and china . therefore the commercial fishing for them is very high . they use it for sushi which is a big part of their diet there . the abundant amounts are also shipped to other countries for consumption including the united states . they are mainly captured the first three months of the year . however , to keep up with the demand for it the process continues all year long .

based on stock assessments in japanese waters current fishing mortality is not expected to cause the stock to drop below b lim in the next five years , and an increase in fishing effort could be sustained .

although the stock is relatively well managed within japanese maritime limits through tac quotas ; reliable estimates of status of the stock are not available in chinese and korean waters hence status of the stock cannot be determined .

marine biology - - found that the squid actually propel themselves with a jet of water , and that they deliberately control their fins and arms to direct themselves . thus , describing them as " flying " is actually pretty accurate . a major downside for the squid , though , is that they have to fly backwards , so they don ' t know whether where they ' re going to land is any safer than where they ' re escaping from .

the researchers had plenty of time to photograph and study the squid , and work out exactly how they stay in the air . yamamoto writes : " once they finish shooting out the water , they glide by spreading out their fins and arms . the fins and the web between the arms create aerodynamic lift and keep the squid stable on its flight arc . as they land back in the water , the fins are all folded back into place to minimise the impact . we have discovered that squid do not just jump out of water but have a highly developed flying posture . this finding means that we should no longer consider squid as things that live only in the water . it is highly possible that they are also a source of food for sea birds . "

qualitative scores have been assigned for this stock due to absence of reliable scientific and management quality information within korean and chinese waters . stock assessments have been conducted on a regular basis within japanese limits but a precautionary score has been applied for the whole stock here due to transboundary nature of the stock , which straddles korean , chinese and japanese maritime limits . management measures could not be evaluated for chinese and korean waters hence precautionary scores are applied for 1 to 3 .

while in the water , a squid can swim using two main methods . one method , like a fish , is fin undulation ( macia et al . 2004 ) . while fin undulation is sufficient for the regular paced movement of a squid , the use of jet propulsion is necessary when the squid needs to move quickly , such as when evading a predator ( macia et al . 2004 ) . the first step of jet propulsion is achieved when water is drawn into the mantle through a wide opening and into the mantle compression chamber ( packard 1969 ) . should a squid need to make a quick evasive move , it can contract its mantle , forcing the water through a slender funnel , creating a jet that will propel it in the opposite direction of the jet stream ( gosline and demont 1985 ) . so where does the flight come from ? sometimes , if the jet propulsion from the squid is strong enough , there is enough force to push it through the water surface and send it flying through the air ( muramatsu 2013 ) .

researchers at the hokkaido university classified the squid’s flight into four main parts . the first step is launching , where the squid uses the high pressure from jet propulsion to break through the surface , folding their arms so as to reduce resistance from the water surface . the second step is jetting , where the squid opens up its arms and fins and travels through the air using the water remaining in its mantle . the third step is gliding where , similar to a flying fish , it uses its spread out arms and fins to help generate lift from the wind and travel further . the last step is diving , where much like any other organism that dives , it folds in its appendages to form a streamline body shape to make entry back into the water a smooth process ( muramatsu 2013 ) .

generally , these creatures can weigh about 1 . 1 pounds ( 500 grams ) and can have a length of up to around 1 . 5 feet ( 50 centimeters ) . the average life span of such a squid is very short ( about 1 year ) because they are so heavily preyed upon by creatures like sperm whales , dolphins , seals , baleen whales and rays . chinese , japanese and other people in the region fish the squid for consumption . also contributing to the short life span , is that they die as soon as they reproduce ( 1 year is usually the time it takes for them to reach sexual maturity , mate , and lay eggs ) .

it is reasonable to think that different enzymes in squid liver can be characterized by the enzyme - specific digestion pattern of myofibrils , which are easily analyzed on sds - page . inhibition spectrum study was the method to identify the proteinase present in squid liver . when myofibrils were incubated with the crude extract in the absence of any inhibitors , mhc and actin were degraded into fragments (

scientists have uncovered a new large species of squid among 70 types gathered during an exploration of the depths of the indian ocean , the international union for the conservation of nature said on monday .

for years , fishermen and sailors have reported seeing squid " flying " across the surface of the sea , and every now and again someone gets lucky and manages to nab a few photographs of cephalopods in action . it ' s only now , though , that marine biologists from hokkaido university have discovered exactly how these squids squirt water out fast enough to propel themselves through the air at up to 11 . 2 metres per second - - faster than usain bolt ' s top speed of 10 . 31 metres per second .

" this finding means that we should no longer consider squid as things that live only in the water . it is highly possible that they are also a source of food for sea birds . "

researchers from the university of queensland played a key role in filming the first video images of a live giant squid in its natural habitat , in lightless water up to a kilometre under the ocean .

the impact of the squid fishery in a multi - gear fishing across all three jurisdictions is difficult to quantify until more information is made publicly available on types of gear used within limits of this fishery .

as a squid moves through the water , they stretch in the mantel area . this is going to force water to be moved through the funnel . you will notice that they move tail first through the water . they are very quick as well as agile in the water . when a squid feels that they are in danger they release a dark color of ink as they try to make their rapid escape .

a squid has gills which is uses to breath through . therefore it doesn’t have to go to the surface of the water for air . they have a very complex body design for a mollusk which makes them very fascinating . they are also simple enough to capture in the water . this is why so many fishermen use squid for bait . it is an attractive way for them to get a variety of fish .

an image from footage taken by nhk and discovery channel in july 2012 and released on january 7 , 2013 shows a giant squid up to 8m long , filmed at a depth of 630m in the sea near ogasawara islands .

what ' s more , the squid can speed through the air at over 11 meters per second . that ' s faster than usain bolt , who averaged only 10 . 3 meters per second in the 2012 london olympics .

a more rigorous study of both government reports and published literature is necessary for chinese waters . studies need to be conducted to evaluate seasonal movements of this stock across all three jurisdictions of korean , chinese and japanese waters . governance measures also remain unknown for this stock in chinese and korean waters . suggest increased data collection to gather information to make an analytical assessment possible in the near future across its distribution range .
