But my blog cannot and will not end with such a vague answer!
Sea lions are a type of seal that have external ear flaps, can rotate their hind flippers under their bodies and "walk" on land. They use long front flippers for swimming and standing, and have LOTS of blubber (or fat).

Fur seals look a lot like sea lions and have almost the same physical characteristics, except they don't have all that blubber to help keep them warm. They have, you guessed it, fur! Both sea lions and fur seals are in the same family and referred to as "eared seals."

warmth out of their fur coats.
True seals, sometimes referred to as "earless seals," are in another family. This includes all other seals except sea lions, fur seals, and walrus. True seals don't have external ear flaps, they use their hind flippers for swimming, they have a lot of blubber, and short front flippers so they slug around on land. Our Atlantic Harbor seals are examples of a true seals.

When put side by side, you can really see the similarities and differences. Here at the New England Aquarium, we currently have Atlantic harbor seals and Northern fur seals and California sea lions.
