A new study has found that elephant seals have to work very hard to stay fat.
The research represents the most complete study to date of the feeding behavior of northern elephant seals. Scientists paid special attention to females of the
species during difficult two-month trips, or migrations, in the northeastern Pacific Ocean.
The seals were found to spend up to 20 hours every day - and sometimes a full 24 hours - in continuous deep-diving to feed on fish. They fed 1,000 to 2,000 times daily to gain the body fat necessary for reproduction and warmth in the cold waters. ....

For deep-diving elephant seals, it takes lots of work to stay fat


Article content
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.
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. They fed 1,000 to 2,000 times daily. ....

There’s no 9-to-5 for female northern elephant seals. After the winter breeding season, the animals spend more than 19 hours and up to 24 hours per day hunting in the northern Pacific Ocean, killing up to 2000 small fish daily to survive, according to a new study of these elusive animals. The work, made possible by cameras and devices attached to the seals’ heads, could also help scientists monitor other deep-ocean life.
“This study is fascinating,” says Jeremy Goldbogen, a marine biologist at Stanford University who was not part of the research. “The advanced technology provides unprecedented levels of detail on where and when the elephant seals forage in a deep, dark ocean.” ....
