Antarctic Killer Whales The orca (orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. the only extant species in the genus orcinus, it is recognizable by its distinct pigmentation; being mostly black on top, white on the bottom and having recognizable white eye patches. Unlike the baleen whales, orcas or killer whales are ‘toothed’ whales, with true teeth rather than fibrous plates for filter feeding. they catch single prey, ranging from fish, squid, penguins, seals, dolphins, porpoises, and even whales, including the largest whale of all, the blue whale.
Antarctic Killer Whales Orcas, also known as killer whales, are found in every ocean but are most abundant in the southern ocean. their population is estimated to be between 25,000 27,000, making them the third most abundant cetacean in antarctica. A tour group visiting bremer bay canyon off western australia's south coast has reported what is believed to be the first sighting of antarctic type b killer whales in the area. This paper provides field descriptions and biological observations of three different forms of killer whale (orcinus orca) that occur in antarctica based on field observations and a review of. One of the most recognizable creatures in the world, let alone antarctica, killer whales are our personal favourites! their beautiful markings, cunning hunting techniques and playful nature make them one of the best animals on an antarctica cruise to observe.

Three distinct types of killer whale, or orcas, can be found in the antarctic, each with a different habitat and diet preference. one type of orca preys almost exclusively on the antarctic minke whale, another on seals, and the last eats fish. Here, we present movement data from type b killer whales, predators of ice seals and penguins [9, 10], which were satellite tagged in antarctica. we document an unprecedented, rapid migration to subtropical latitudes and back. They are odontocetes or toothed whales and while they are quite small compared to the great baleen whales (mysticetes) they are at the very top of the antarctic food chain due partly to their formidable array of teeth, but most of all due to the fact that they often hunt in packs or "pods". Pack ice killer whales are a unique type of orca that live in antarctica – and there are fewer than 100 left. a rare 'pack ice' killer whale has been filmed swimming in the snow by researchers who are trying to protect this unique population.
