Diving Deep With Elephant Seals - Randall Davis

For as clumsy and cumbersome that they appear to be on land, 4,000-pound elephant seals are powerful and graceful swimmers that can dive over 2,600 feet below the ocean’s surface while hunting prey such as the bioluminescent lantern fish. National Geographic grantee Randall Davis has been using a video camera to study the pinniped’s deep-sea feeding habits.
