Antarctica Wildlife

Antarctic Birds
Millions of seabirds breed along the coast and offshore islands of Antarctica. To survive in the biting environment, Antarctic birds have waterproof plumage, and large compact bodies with a dense layer of fat under their skin. There are nineteen species of seabirds that breed along the continent. Due to the shortage of snow-free nesting regions, most seabirds tend to procreate in large, impressive concentrations, making for ideal viewing conditions for the bird enthusiasts. The birds will migrate north as the summer months come to an end, spending the winter in more temperate climates. Penguins
One of Antarctica's most familiar wildlife, penguins are considered by many to be the continent's signature species. They spend over 75% of their lives as sea where they are most comfortable. Their bodies are designed for swimming. Powerful paddle muscles and a compact hydrodynamic body shape allow penguins to swim up to 25 mph. Impressive and elegant in the water, by contrast, penguins awkwardly waddle and hop once ashore. While seventeen species of penguins can be found in the subantarctic regions - including coastal islands - only four types of the flightless birds breed on the continent itself: the Emperor, Adelie, Chinstrap, and Gentoo penguins. Antarctic Seals
Much of the early exploration of Antarctica and the Southern Ocean was do to the search for new seal communities. During the 19th and 20th centuries, many seals were hunted for their valuable skins and oils. Entire populations of species were driven to the brink of extinction. Thankfully, today, the seals are protected by a collection of agencies, and their numbers have continued to thrive. Because of the nutrient-rich feeding regions and the lack of polar bears, the Antarctic has a much larger seal population than the Arctic. Most of their life is spent in water, but seals must return to land to breed. The best locations to view their breeding grounds are on the pack ice surrounding Antarctica, or along the coastal shores of the northern islands. Whales
Whales are divided into two main groups: toothed and baleen. The only toothed whales found in the Antarctic are the Orca and the Sperm whale, while a variety of baleen whales have been sighted: Blue, Fin, Humpback, Minke, Sei, and Southern Right. Unlike the other wildlife of Antarctica, whales do not breed in the region. However, they do take advantage of the nutrient-filled waters in the austral summer, traveling great distances from their temperate breeding waters in the north. Like seals, several species of whales were hunted until near extinction in the mid-1900s. While regulations have been placed on whaling activities, these magnificent giants have not seen their populations recover as well as the seals. Today, the entire area surrounding Antarctica is recognized as a whale sanctuary.
