Sperm whales may team up and hunt collaboratively

Sperm whales hunt squid in groups

In a new study, Professor Bruce Mate from the Hatfield Marine Science Center in Oregon working with Jorge Urban of the Autonomous University of Baja California Sur, placed data-recording tags on sperm whales feeding on Humboldt squid in the Gulf of California.

The tags use GPS and depth sensors to track the whales' movements in three dimensions for up to 28 days, then detach and float to the surface.
