Dolphin Anatomy

Dolphin anatomy is much the same as the anatomy of other whales.

It is all about adaption to the life in the water.

Dolphins and other toothed whales have got streamlined bodies, flippers, flukes and blowholes, just like baleen whales.

Like other whales, they've also got ribs around their lungs and many species have got humps or dorsal fins.

As opposed to the baleen whales, however, toothed whales (including dolphins) have got large melons in their foreheads, which produce the clicks they use in echolocation.

As opposed to dolphins, large baleen whales don't use echolocation and consequently lack the melons.
