Four differences between seals and sea lions

According to the article What’s Left of Patagonia at Interesting Thing of the Day, both seals and sea lions are pinnipeds, or “fin-feet,” but…

  1. Sea lions have much larger front flippers than seals.
  2. Sea lions have back flippers that can rotate underneath them; seals don’t.
  3. When on land, sea lions can walk on all four flippers, whereas seals sort of slide or bounce along on their bellies.
  4. Sea lions have external ear flaps, whereas seals have ear holes but no outer appendage.
