. Animal life. Zoology. 54 ANIMAL LIFE of its time in the sea near the coast, and only going ashore to rest and to bring up its family. The body is thick in front and flattened behind. The tail has almost disappeared, and on either side of it the hind limbs are held rigidly out at full length. Between the fingers and toes the skin has grown so as to convert the fore-limbs into paddles and the hind-limbs into a propeller. On land a seal shuffles awkwardly on its belly, only using its hands if pressed; but at sea the flattened hind-limbs, together with the lateral muscles. Fig. 9. —The While Sea

The forepaws are used for steering. The porpoises and dolphins, the baleen and toothed whales, are as perfect in the art of swimming as any fish. Their bodies, denuded of hair, are usually of a build so completely adapted for cleaving the water that boat-builders could design the lines of their craft from models of whales. The head is a cone pointed in.
