Full Answer

The style of swimming that permits backward movement is called anguilliform locomotion and uses undulatory movements. A fish employs several swimming styles depending on their environment. Flying fish evolved to glide above the water by flapping their fins. Most species of fish are color-blind, and some species can live 50 years or more. Porcupine fish inflate themselves by pumping water into special pockets in their body when in the sea or by pumping air into the pockets when they are above the surface. A fish breathes by taking in oxygen from the surrounding water.

    Why do fish swim in schools?

    A:

    According to North Carolina Aquariums, fish swim in schools because schooling protects them from predators, encourages reproduction and makes it easier to find food. Schooling also conserves energy, as each fish drafts in the wake of the fish ahead of him. This makes it easier for fish to swim long distances without exhaustion.
