No. Only mammals have belly buttons.
All placental animals have belly buttons.
Mammals, yes.
Dolphins are placental mammals. All placental mammals have bellybuttons of some kind.
Cats are placental mammals, and all placental mammals have bellybuttons of some sort.
As a matter of fact, dolphins do have bellybuttons. All mammals have them because that is where their umbilical cord was connected.
Yes, they do eat bellybuttons. It's their favorite food!
Because animals hatched in eggs do not have an umbilical cord, therefore. do not have a bellybutton, the scare left after the umbilical cord is cut. Some animals not hatched from eggs come out of their mothers in a sack and the sack is licked off by their mothers, therefore are left without a bellybutton.
Yes.
no
No, eggs do not have bellybuttons. Bellybuttons are the remnants of the umbilical cord connection in mammals, which provide nutrients from the mother during development. Eggs, particularly those laid by birds and reptiles, are self-contained with all necessary nutrients for the embryo. Once fertilization occurs, the developing embryo is nourished by the yolk inside the egg, eliminating the need for a bellybutton.
Umm, no ;)
