What you’ll see diving here:

Cocos Island
Among Cocos Island’s many attributes is a startling degree of biodiversity. This Island’s world-renowned waters explode with life, including innumerable white tip reef sharks, schooling hammerhead sharks, dolphins, mantas and marbled rays, giant moray eels, sailfish, and of course the occasional whale shark. Other common encounters are large schools of jacks and tuna, silky sharks, silvertip sharks, marlin, Creole fish, green turtles and octopus. Diving here is challenging and action-packed.

Malpelo Island is home to an important coral formation as well as a large variety and quantity of marine creatures. Of special interest are hammerhead sharks with awe-inspiring schools of 300 individuals commonly encountered. The two most outstanding phenomena in Malpelo are the huge numbers of free swimming and cluster moray eels along with the colossal congregations of silky sharks that often join with hammerheads to form enormous mixed schools. Extraordinarily, Malpelo is one of the few places that a diver may chance upon the elusive Small Tooth Sand Tiger, which is also known as the Spotted Ragged-tooth shark (Odontaspis ferox).
