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.
