don't have body hair because they need to swim as fast as they
can to catch fish, their main source of food. They also need to
be able to evade their predators, like the evil sharks found in
the ocean. The name Dolphin refers to the species that have a
beaklike snout and slender, streamlined body, which has
developed over millions of years through evolution to enable
them to swim at high speeds. Unlike our skin, the Dolphins' skin
made of live cells, unlike our dead skin and because of this
they have no protection from bumps or bruises.
