This blubber also helps in the streamlining of their shape, allowing these torpedo-shaped animals to chase their prey underwater with amazing effectiveness.

Pinnipeds also have a larger relative volume of blood than other mammals allowing them to store large amounts of oxygen in their blood on very deep and prolonged dives with dives of up to metres and 2 hours having been recorded. The 33 living species of pinniped are divided into 3 families: The Otariidae differ from the Phocidae in several ways but perhaps the most noticeable ones are that otariid seals have external ear flaps, generally walk on both their hind and fore flippers, and propel themselves through the water by their fore flippers with a sculling motion.

Phocid seals on the other hand do not have visible ear flaps, drag themselves along land by their fore flippers or bodies and use their hind flippers to propel themselves through the water, their fore flippers being used for steering.
