Birds use their hollow bones and feathers as wings to fly. Snakes use their muscles, ribs and backbone to apply the pressure on the ground but the scales grip the surface and help it move forward. Snails have a strong muscular foot and they move forward by making rhythmic pulses of contraction and expansion. Fishes swim through water using their fins and tail to maintain their balance and steer respectively. Cockroaches have 3 pairs of legs and a pair of wings to move and fly. Earthworms grip the surface using fine bristles and push their body forward using the muscles of the body.
