The hunting of the squid

Two scientific teams have joined forces to find out just how the biggest predator in the sea, the sperm whale, finds it fast-moving squid prey. One team, led by William Gilly at Stanford University, was tagging the two-meter jumbo squid (Dosidicus gigas, not to be confused with the much larger giant squid Architeuthis dux), squid, while Randall Davis's team from Texas A&M University was tagging sperm whales. Now the joint team can "watch" as the animals, which normally congregate at different depths, cross paths and become steps in the same food chain.
