White-tipped Reef Shark (Triaenodon obesus)
ECUADOR. South America
RANGE: Common in the entire archipelago. North to Costa Rico including offshore islands, also tropical and subtropical Indo-Pacific.
They inhabit rocky reefs and boulder strewn slopes. Nocturnal and generally lie motionles during the day on sandy bottoms near rocky outcrops or under ledges or in caves. They feed primarily on reef fish, octopuses and crustaceans. They are particularly adept at wrenching prey from cracks, holes and other recesses in the reef.
