Answer:
1.An earthworm moves using circular and longitudinal muscles, as well as bristles called setae. The earthworm can push the setae out of its body to grab the soil around it. To move forward, the worm uses its setae to anchor the front of its body and contracts the longitudinal muscles to shorten its body.
2.Land snails move by gliding along on their muscular foot, which is lubricated with mucus and covered with epithelial cilia. This motion is powered by succeeding waves of muscular contractions that move down the ventral of the foot. ... Snails secrete mucus externally to keep their soft bodies from drying out.
3.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.
4.Birds obtain thrust by using their strong muscles and flapping their wings. Some birds may use gravity (for example, jumping from a tree) to give them forward thrust for flight. Others may use a running take-off from the ground.
5.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.
6.Snakes slither to move around because they have no legs. They rely on their muscles and scales. ... The scales drag against the ground to help move the snake forward. Finch said that a snake's strong muscles help it lift some scales and allow it to move along rough surfaces like branches and trees.
