Some common animals found in the Antarctic are several species of penguins, several seal species and multiple types of birds. Several types of marine life thrive in the waters of the Antarctic, including krill, whales and fish.
Antarctica boasts six species of penguins: adélies, emperors, gentoos, macaronis, rockhoppers and chinstraps. These penguins have dense, downy feathers coated with an oily substance that prevents water and cold from sinking down to the skin. A thick layer of fat protects them from the cold and keeps heat trapped close to the body. Emperor penguins, the largest of any species, grow up to 44 inches tall. The males take care of the eggs during the coldest weather, while the females feed. The small rockhopper penguins live on Antarctic islands.
The majority of seals live in Antarctica or on the surrounding polar islands. They live mostly in the water, surviving the bitter cold with their dense fur and thick blubber. Despite their large size and flippers, they can maneuver fairly well on land.
A range of fish species live in the Antarctic waters from the naked-head toothfish and rakery beaconlamp to the Antarctic dragonfish and Warming's lantern fish. The latter two are deep-sea species, swimming at depths of 5,000 to 6,000 feet.
