A Toothy Grin

The toothy maw of a great white shark has populated the terrified fantasies of many a beachgoer. But these intelligent predators have been hammered hard by people over the years. Targeted for the shark fin trade, illegally hunted, and caught as bycatch in abandoned fishing gear, great white shark populations have been in decline for decades.

There is some hope, though. Protections at the state and national levels have helped relieve the pressure on great white shark populations. Recent studies have noted an uptick in white shark numbers along the West and East Coasts of the U.S. (See "Great White Sharks Thriving in U.S. Waters.")
