10 Unusual Facts About Penguins You May Not Know

Animals, Lists, Nature, Other, Weird

Penguins (family Spheniscidae, order Sphenisciformes) are a group of flightless, aquatic birds residing in the Southern Hemisphere, specifically in Antarctica. Well-adapted for life in the water, these birds have countershaded white and black plumage, and their wings have evolved into flat, paddle-like flippers. They feed on squid, fish, krill and other forms of sealife. Penguins spend half of their lives in the oceans and half on land. This list contains 10 unusual facts about penguins you may not know.

Penguins play crucial roles in ecosystems on land and in the ocean. Penguins – eggs, young and adults – serve as food for predators such as seabirds and leopard seals in cold areas, along with crabs, leopards and foxes in warmer climates. By chasing after krill, squid and fish, penguins affect populations of prey wherever they hunt. These birds carry nutrients between sea and land, and enrich both with their poop.
