Maximal Feeding Depths of Walruses
Walruses (Odobenus rosmarus) feed mainly on benthic invertebrates in waters less than 80 m deep, and they have been presumed to be incapable of diving to greater depths. Reported here are seven walruses whose stomachs contained significant amounts of benthic sediments and food, some of which must ha...
