Grey Reef Shark in the Line Islands

Grey reef sharks (Carcharhinus amblyrhynchos) are among the most versatile and tough predators on a Pacific coral reef, but they are also among the most vulnerable species, as they are threatened by wasteful fishing practices like shark finning. They're also very sensitive to human presence, fleeing reefs when people settle along the coasts and preferring more isolated areas. Where you can find them, they can be quite bountiful, as Dr. Stuart Sandin writes in his blog post "Where the Sharks and Snapper Roam." Read it here.
