What is the difference between seals and sea lions

I saw a lot of sea lions at Anacapa Islands but they looked just like seals so I asked mommy what is the difference between a sea lion and a seal?

Seals are furry where as sea lions are mostly skin-covered.

Sea lions have small flaps for outer ears where as seals lack external ears altogether.

Sea lions are noisy. Seals are quieter.
