New research shows that elephant seals can dive more than a mile under water, according to this article. Researchers at the University of California, Santa Cruz published their findings in the journal PLoS ONE on May 15. The study focuses on the annual migrations of adult female elephant seals, with data from nearly 300 animals. It is one of the largest datasets available for any marine mammal species, revealing their movements and diving behavior at sea in unprecedented detail. One dive was recorded at an ear-popping 5,765 feet.
Female northern elephant seals make two large feedings trip during the year in an effort to store up fat reserves before giving birth. Seals can choose from several different techniques in their feeding arsenal to meet dietary needs. It is because of this that seals might be less susceptible to climate change than previously thought.
