Can sea lions hear?
Hearing: Sea lions hear both above and below the water’s surface, although they hear better under water. Studies show sea lions can hear frequencies up to 70,000 Hz, but tend to vocalize within a range of 100 to 10,000 Hz. This is comparable to humans who have a hearing range of 20 to 20,000 Hz.
Why do sea lions have ear flaps?
