Answers
A cockroach moves its legs with the help of muscles near the limbs. It uses its breast muscles to move its wings and fly. A cockroach can walk, fly and even climb.
Snails move with the help of their muscular foot. They produce a wave like motion along their foot, contracting and stretching their muscle which pushes the body of the snail against the surface moving in the forward direction.
Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. This motion moves them forward through the water. Fish use their back fin, called the caudal fin, to help push them through the water.
