Answer 2

Yes, dolphins have belly buttons because they are mammals. They have umblilical cords just like humans. In addition, whales and porpoises have belly buttons. The umbilibal cord breaks when the mother turns in the water.

The belly button of a dolphin is called and umbilicus, and it does not look like a human belly button. You can see an image of the umbilicus here:

Answer 3

All of the cetaceans (whales, dolphins and porpoises) have very small belly buttons.  Even an 80 foot (dead) blue whale (Balenoptera muscalus), which has huge everything else, has a belly button about the size of a golf ball, and (living) Pacific gray whales (Eschrichtius robustus) have navels about the size of marbles.

The only dolphin navels I have had the chance to observe carefully in the wild are a bottlenose dolphin (Tursiops truncatus), which I noticed because it was an "outie" about the size of a pencil eraser, and a common dolphin (Delphinus delphus) that I remember because its navel was so small I spent several minutes looking for it before finding it, with the dolphin held upside down in my arms.  I knew it was there somewhere, but instead of the usual unbilical slit, there was just a very tiny "innie."
