Chinstrap penguins in Antarctica have adapted to harsh conditions by sleeping in a very unusual way. They sleep in short bursts – about four seconds at a time. By doing this thousands of times daily, they get about 11 hours of sleep a day. Chinstrap penguins get their name from the thin black line under their chins, which looks like a strap holding on a black hat or helmet. Like other penguins, they spend much of their time in the water, catching fish to eat. But when the time comes to raise their young, they return to land.
Raising young penguins is a challenge. The eggs are often laid in nests made of small rocks to keep the eggs from freezing. One parent takes care of the nest for long periods, while the other parent hunts for food.
