Which animals are bald or naked?
Some mammals and birds are born with fur, hair, or feathers – these babies or young are called precocial because they already have some features like their parents and can usually move independently soon after birth.
There are also many mammals and birds that are born pink and without fur, hair, or feathers. They are called altricial because they are helpless, usually blind, and hairless or featherless. They grow their outer covering as they mature and age.
Some mammals, and humans, are born naked and grow hair on some parts of their body. Some animals appear to be naked but, if you look closely, they have hair, like the rhinoceros, hippopotamus, and elephant, which have sparse hair or tufts (small clumps) of hair on their ears or tail. Other animals, like reptiles and fish have scales or tough skin.
Some animals have the word bald in their name, but they are not.
