Unlike true seals, sea lions have small outer ear flaps. This is one of the easiest ways to tell them apart.
Kid Decode: Sea lions have tiny ears that actually show.
3. Sea Lions Can Walk Better on Land

New Sea Lion Fact for Kids
Sea Lion Brains Have a Special Connection for Vocal Flexibility
Scientists used brain scans to discover that California sea lions have a direct brain pathway for controlling sounds, bypassing automatic breathing centers. This may help explain why sea lions can learn to make new sounds. The study compared sea lion brains to coyote brains to understand vocal flexibility.
The Weirdest Sea Lion Fact
