The right answer is that penguins are not mammals. Mammals are classified as vertebrate of the class Mammalia that nurse their young with milk and give birth to live animals. Penguins don’t do either as they lay eggs and feed their young with regurgitated food such as fish, krill, and squid.
One of the next things we wondered was: is a penguin a mammal?
Penguins are not mammals, but birds. A mammal is a vertebrate belonging to the class Mammalia, which is characterized by things like three bones in the middle ear, a neocortex in the brain, mammary glands, and true hair. The female members of this class feed their young ones with milk, which is produced by the mammary glands.
The group behavior when it comes to protecting their young ones and conserving heat is also another reason why penguins are often mistaken as mammals. To do these two things, penguins usually huddle close together in groups with the young ones in the middle sections for maximum protection.
Do penguins camouflage?
Penguin Camouflage The distinct black and white coloring of penguins is a type of camouflage called countershading, which helps penguins hide from predators and hunt prey. The countershading observed in penguins generally consists of black feathers distributed atop their heads, backs and flippers to help them blend in with the darkness of the ocean when viewed from above.
How do Penguins camouflage in open water?
It might stretch your imagination to think of a penguin being camouflaged in open water, however, marine habitats are the best at providing optimal lighting for a countershaded animal to blend in. When an animal is in the water, the light source is always directly overhead, making lighter colored objects closer to the surface harder to distinguish.
The advantage, according to many books and articles is that the birds are harder to see from above. But, when you look at underwater footage of penguins, they often do not really blend in with the environment that well. Here are some birds that are true masters of the art of camouflage….
What are the differences between penguins and other birds?
Birds do not have teeth, they have beaks or bills. Penguins have sharp beaks that have spines in their mouths that face backward. A penguin’s beak helps it to catch and eat fish.

What do penguins look like on land?
At sea only the part of the plumage that faces the sun is black. And on land, the penguins generally lay down on their tummies or huddle together backs exposed.
Do penguins lay eggs or lay feathers?
