True seals have internal ears and use their rear flippers for swimming. The fore flippers are used for steering. Different species are found from the equator to the poles. The largest are the elephant seals (two species).
Eared seals are the sealions and fur seals. They have external ears and use the fore flippers for propulsion in water. They can tuck their hind flippers under on land and use them to help move wuite rapidly on the beach. True seals cannot do this but hunch along rather sluggishly.

I think this is the answer:
Seal as the sea lion is a pinnipedia, but it has different characteristics; in the first place it does not have external ears, he is large approximately the half of the marine lion and is adapted to colder waters.
Additionally, true seals do not communicate by "barking" like the fur seals and sea lions of family Otariidae. They communicate by slapping the water and grunting.
Ciao!
