Species of Penguins

There are a total of 18 recognized species in the penguin family, scientifically known as Spheniscidae. These aquatic flightless birds are exclusively found in the southern hemisphere, with some species living in colder regions such as Antarctica while others inhabit temperate zones. Of the 18 species, 11 are considered globally threatened.

Penguins have evolved for life in the water, with flippers instead of wings and countershaded dark and white plumage to help them blend in with their surroundings. They mainly feed on krill, fish, and squid, which they catch while swimming underwater using their powerful jaws and spiny tongues.
