Upper jaw is the skull bone. Lower jaw bone (Mandible) is the only one skull bone which is movable. Fishes have fins, have streamlined body so that they can easily swim in the water. Ribs are very hard and they protect the heart from the injuries or protects other delicate organs inside the chest. Snail shows very slow movement because movement is done by the muscular feet. Cockroaches have outer skeleton, can fly in air. This outer skeleton is made up of number of plates which helps them in the movement.
