bigeye trevally (fish) in Kimbe Bay, Papua New Guinea

The Better to See You With

A bigeye trevally (Caranx sexfasciatus) casts a wary eye on WHOI biologist Simon Thorrold, who photographed this and many other species during a recent research trip to the coral reefs of Kimbe Bay, Papua New Guinea. During the day, bigeye trevallies, which are usually two to three feet long, typically move slowly in schools of 1,500 or more. At night, they disperse as each fish forages for crustaceans or small fish. Thorrold is leading a long-term study of the movement of fish larvae among different reefs in the bay.
