Massive school of fish completely surround scuba divers

While visiting Cabo Pulmo in Mexico, world renowned for its incredible scuba diving, these divers got to enjoy an unforgettable dip in the Sea of Cortez among hundreds of thousands of jacks - medium size fish that look much like a tuna. Once engulfed by this enormous school they appear to completely ignore the divers presence and carry on with their purpose, which is to stay in the group to avoid predators.
