Diving Baitball Dolphins Tuna Sharks 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, silver tip sharks, marlin, Creole fish, green turtles and octopus.

This phenomenon occurs when the little bait fish, upon being hunted, seek protection by forming a furiously spinning silvery ball. This is an attempt of a small species to intimidate and confuse a predator.

In a bait ball you can find different bait fish and different hunters. Sometimes the bait fish will be trapped between the surface and the hunters below. This is when the boobies and frigate birds will join the feast. These special events can happen anywhere and at anytime.
