Penguins are flightless marine birds that are loved by many wildlife lovers and kids. There are 17 species of living penguins. Majority of the species are found endemic to the southern hemisphere where one species called Galapagos penguins live near the equator. Even though the species are different they have the common coloring in the body with white front and black back body.
Watching penguins on TV or in a zoo can be a confusing experience. While they look like birds in a matter of appearance, penguins do not fly. But if you look up the definition of penguins, they are known as marine birds in zoological descriptions. You must have thought why are penguins birds? Indeed, the question becomes even more significant when you see penguins swimming in the water like fish or waddling on the Antarctic ice like two-legged animals.
If you have ever seen a penguin walk or swim, you must have wondered why can’t penguins fly. After all, penguins flippers look like wings, and their bodies are covered in feathers. Even when penguins swim through water, the swimming motion makes it look like they are flying. The reason behind the flightlessness of penguins goes into their physiology, biology, and evolutionary traits.
Penguins are one of the few flightless birds, but they are unique because they have evolved to swim and hunt underwater. Penguins also live in extreme weather conditions of the Antarctic region which makes it difficult for them spend energy in flying and instead of wings, they have evolved to grow flippers that help them in swimming.
