Antarctica's primary animal species include penguins, with the Emperor Penguin being the most notable. These iconic birds are adapted to the harsh climates of Antarctica, exhibiting traits such as excellent swimming capabilities and social behavior, which facilitates survival in extreme conditions. Other notable species include seals, such as the Weddell seal and leopard seal, and numerous seabirds. While its ecosystem is relatively limited compared to other continents due to extreme conditions, Antarctica remains vital for global climate regulation and biodiversity conservation, with ongoing research efforts to understand its unique environment.
