They’re some of the most popular zoo animals– it’s fun to watch them swim and play. Their sleek bodies and whiskers are adorable. They’re… uh, seals? Or maybe sea lions? What’s the difference, anyway?

Seals and sea lions are relatives– they’re both members of the pinniped family, along with walruses. But while they have a lot in common, there are some key differences that you can use to tell them apart. Sea lions bark loudly, have visible ears, and can use their flippers to walk (or waddle) on land. Seals, on the other hand, are quieter, have small ears flush to their heads, and stick to the water. Can you tell which is which in this photo?seal-sealion
