What is the difference between a seal and a sea lion?
There are quite a few differences, some of which are easy to see. First, sea lions have small external ear flaps. Seals have no external flap; however, sometimes their ear hole is visible. Second, sea lions can rotate their rear flippers forward so that they can walk on land, using all four flippers. Seals cannot rotate their back flippers forward, so they drag their rear flippers and crawl on land. Also, sea lions have long wing-like front flippers with no claws, seals have short front flippers with claws.
