How do sea animals protect themselves from their predators?
Through the process of natural selection different species have evolved different mechanisms of protections. Some have speed, some cunning, some size, some camouflage. Dolphins are intelligent creatures whose only natural predators (other than man) are sharks. They use their cunning and speed to fight them off. Loggerhead seaturtles have evolved thick skulls to protect themselves against the same predators and have been known to fight back by striking at the gills or taking an upright posture in the water so as to make it more difficult for the shark (tiger sharks are the only sharks known to make seaturtles a regular meal) to get a good grip on their wide shell. Other animals use their camouflage abilities to blend into the background.
