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

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.
