Diver swims straight into gigantic school of hammerhead sharks

Hammerhead sharks are menacing looking animals that patrol the waters of the Galapagos Islands in huge numbers. Enormous beasts, with a mouth full of razor sharp teeth, they strike fear in the hearts of many who do not understand them. Despite their fearsome reputation, they pose no danger to scuba divers or swimmers. There have been very few unprovoked attacks on humans and there has never been a documented case of a fatal injury inflicted by a hammerhead shark.

Hammerheads are graceful and powerful creatures.
