Sperm Whale Takes a DiveM.M. Sullivan
Sperm whales are the largest extant toothed whale, and have the largest brain of any animal on record.
Their favorite meal is large squid, and they don’t mind searching the depths of the ocean to find some. Sperm whales can dive up to several thousands of meters deep, and remain underwater for over an hour — they are the second-deepest diving of all whale species.
