 * __HOW DO FISH SWIM?__**

Answer the question below, append new answers to the top of this page. _ __Response 1:__ A fish propels itself through the water using a muscle located on the back of the fish. They use two muscles located on the side of there body for turning and a small amount of speed. They use vertical fins to keep themselves stabilized and from rolling onto there back. It moves through the water in a similar way that humans walk on land. A human puts one foot down and pushes off the ground to move. A fish uses its fins to push itself through the water.

__Additional Responses:__ Many fish swim by contracting and relaxing muscles called myomeres, alternating on each side of the body starting at the head, moving down to the tail. As a fish does this, the body is moving from side to side resulting in a series of waves traveling down the fishes body. The rear part of each wave pushes against the water propelling the fish forwards.

Myomeres: Blocks of skeletal muscle tissue in the shape of v's or w's.
