Besides dolphins and killer whales, what other animals can be seen in Hauraki Gulf Marine Park?
Killer whale The killer whale or orca ("Orcinus orca") is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
Surplus killing Surplus killing, also known as excessive killing and henhouse syndrome, is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then cache or abandon the remainder. The term was invented by Dutch biologist Hans Kruuk after studying spotted hyenas in Africa and red foxes in England. Other than humans, surplus killing has been observed among zooplankton, damselfly naiads, predaceous mites, martens, weasels, honey badgers, wolves, orcas, red foxes, leopards, lions, spotted hyenas, spiders, brown and black and polar bears, coyotes, lynx, mink, raccoons, dogs, and house cats.
