The marbled ray is in the stingray family and is a very common sight at Cocos Island. The spine at the base of the tail can deliver a nasty wound. If you step on a ray, its natural defense is to quickly jab its tail upward, stinging its attacker. You should be careful to shuffle your feet when walking on shallow sandy bottoms. Marbled rays have small grinding teeth used to feed on shrimps, crabs, worms and snails. They bear live young that look like miniature versions of the adults. Video by Vic

Getting you close to the action in Cocos Island is what we do best. All of the equipment, boats, nitrox, and cameras are nothing if you don’t have an experienced guide that knows how to take you to the right place at the right time. Our guides are the best in the world and they know sharks like a pilot knows an airplane.
