an earthworm for instance has bristales under its body which helps it to move. it holds on to the ground with its tail and expands itself so that the head moves forward by stretching oc muscles . next keeping its head fixed it draws up its tail by contraxing. this alternate contraxion and expansion helps to move the earthworm forward.
hope this will help.!!
