ELEPHANT SEALS

May 16, 2021

For elephant seals - one of the most distinctive of the 33 species that comprise the world's seal family - it is hard work to stay fat.

About:

  • Scientists have conducted the most thorough study to date of the unique feeding behavior of northern elephant seals, focusing on the females of the species during arduous two-month post-breeding migrations in the northeastern Pacific Ocean.

  • The seals were found to spend upwards of 20 hours every day - and sometimes a full 24 hours - in continuous deep-diving to feed on multitudes of small fish, rather than the larger prey favored by other deep-diving marine mammals, to gain the body fat essential for successful reproduction and insulation in the frigid depths.
