Full Answer

Penguins are birds that originate from the Southern Hemisphere. They typically spend a lot of time standing, although they occasionally lie down to sleep. Different species have varying sleeping periods and sleeping methods. Many penguins prefer to take short naps only. Fairy penguins and a few other species go to the shore each night to rest for a few hours in small holes. Other species spend a lot of time at sea, living up to 9 months or more every year without visiting the coast. They have to sleep in the water as they spend most of their time in the ocean.

Penguins have a black-and-white coloration known as counter-shading, which they use to camouflage themselves in the water. Their anatomy is well adapted to life at sea. Their white torso blends well with the bright surface of the water, whereas their inky back merges with the raven darkness below them. This concealment helps them avoid predators as well as catch prey. Their legs are located at the back of their bodies, allowing them to maintain an upright position on land.

    How do penguins care for their young?

    A:

    Penguins raise their chicks with dedication from egg to adolescence, when they are old enough to enter the water. According to Sea World, scientists believe the different coloration of penguin chicks encourages parenting behavior in adults. Both parents feed their chick, which they recognize by its call, by regurgitating food into its mouth.
