However, there is an abundance of other forms of wildlife, such as whales, seals, penguins and other birds. Penguins are the most common birds in the Antarctic. They live in colonies and survive in the harshest conditions. Out of the seventeen existing different species of penguins, two of them are permanent residents on Antarctica – the emperor and Adélie penguins. Others, like the macaroni, gentoo and chinstrap, breed on the northern tip of the Antarctic Peninsula, where the conditions are not that harsh. King penguins only breed on the warmer northern islands.
