are the stars of Antarctica. They
represent half of the bird population of Antarctica, nine tenths
of its biomass. They depend on the sea for their food, devouring
about 4.7 million tons a month of crustaceans, fish and squid. While
penguins dominate the bird population, other groups include tube
nosed petrels, cormorants, albatrosses, skuas, gulls and terns.
One might infer from these enormous concentrations of sea birds
that they are invincible, but they are not. The long isolation of
Antarctic birds has produced an extraordinarily innocent and docile
avifauna, a quality that is attractive to tourists, but leaves them
highly vulnerable to harm and mismanagement.
Mammals that inhabit Antarctica include:
Fur Seals, Sea Lions, Seals, Whales such as the Fin, Minke, Humpback
Sperm and Killer Whale.
