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]

The most common lichens are Usnea and Bryoria species. Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis) are found on the northern and western parts of the Antarctic Peninsula, including offshore islands, where the climate is relatively mild.
In contrast with the Arctic tundra, the Antarctic tundra lacks a large mammal fauna, mostly due to its physical isolation from the other continents. Sea mammals and sea birds, including seals and penguins, inhabit areas near the shore, and some small mammals, like rabbits and cats, have been introduced by humans to some of the subantarctic islands.
There are also many different animals that live in the sea water near polar regions. Squids are one animal that live in both Antarctica and the Arctic. They are the food source for other large animals such as the male sperm whale. [21] There is also a wide variety of fish in the polar regions. Arctic cod is a major species in the Arctic.
The citizen science scheme by WWF and British Antarctic Survey aims to help conserve walruses in the face of climate change.
Arctic terns breed in the arctic and subarctic and winter in Antarctica. Like many birds, seabirds often migrate after the breeding season . Of these, the trip taken by the Arctic tern is the farthest of any bird, crossing the equator in order to spend the Austral summer in Antarctica.
