What are facts about spotted seals?

They are one of the best swimmers in the world because of their flippers and fins which allows them to glide fast through the water.

Seals, or phocids, are called seals because there nostrils 'seal' at rest while swimming, they have internal ears only, they propel themselves with their rear tail fins and they can hold their breath, and warm blood, in some extreme environments.

Sea-lions differ with external ears, front flipper propulsion and a useful pelvis allowing rear leg rotation below the body.

Think of seals as slugs and sea-lions as bears that swim
