Penguins are flightless birds that are known for their distinctive black and white plumage. They are adapted to life in the water and are excellent swimmers, with some species able to dive to great depths in search of food. Penguins primarily inhabit the Southern Hemisphere, with the most well-known species found in Antarctica.
These birds often form large colonies, breeding in densely-packed groups. They have a variety of strategies for keeping warm in cold climates, including huddling together and having a layer of insulating feathers.
Penguins feed on fish, squid, and krill, with different species having unique hunting techniques. They are also known for their waddling walk on land and sliding on their bellies over ice and snow.
