Why don't animals have belly buttons?

They are attached to an embilical chord too when they come out so why don't they have a belly button like we do?? Even furless animals you can't see one.

All mammals, and only mammals, have belly buttons. Most animal belly buttons are neither "innies" or "outties," the mark is flatter then in most people. Also frequently covered wtith hair, another mammal trait.

Still, if the animal you're looking at is a mammal the belly button is there and you will see it if you look hard enough.

(There is a small group of primitive mammals, the monotremes that due not have belly buttons. Duck billed platypus and echinids belong to this group.)
