The following is a list of native wild mammal species recorded in Antarctica. There are 23 mammal species in Antarctica, all of which are marine. Three are considered endangered, one is vulnerable, eight are listed as data deficient, and one has not yet been evaluated. [1] Domesticated species, such as the dogs formerly present, [2] are not ...
At least 235 marine species are found in both Antarctica and the Arctic, ranging in size from whales and birds to small marine snails, sea cucumbers, and mud-dwelling worms. The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents. [8]

Emperor penguins inhabit the compacted ice along the coast of Antarctica with some colonies established up to 11 miles inland. Unlike a number of other penguin species that may visit the continent ...
The birds that do breed go to the Arctic between May and July. One of the known birds is the snowy owl, which has enough fat on it to be able to survive in the cold temperatures. In the Antarctic some invertebrates that exist are mites, fleas and ticks. Antarctica is the only continent that does not have a land mammal population. [17] There are ...
Other birds like petrels, sheathbills, and gulls also eat the chicks. Dogs preyed upon penguins while they were allowed in Antarctica during the age of early human exploration as sled dogs, but dogs have long since been banned from Antarctica. [96] Instead, adult penguins are at risk at sea from predators such as sharks, orcas, and leopard ...
The citizen science scheme by WWF and British Antarctic Survey aims to help conserve walruses in the face of climate change.
The Arctic food chain would be disrupted by the near extinction or migration of polar bears. Arctic sea ice is the polar bear's habitat. It has been declining at a rate of 13% per decade because the temperature is rising at twice the rate of the rest of the world.
