The Goliath groupers can reach a weight of 360 kg and 2,7 meters in length. That is large enough so that they can draw a snorkeler, like the man in this video, who loses his temper when it loses its prey from a few Blackfish Goliath.

“What's a ruffian supposed to do?, When a fish is injured in the neighborhood;” says the oceanographer and National Geographic researcher, Sylvia Earle. “Time for dinner!”

The incident took place in a wreck in the Northern Gulf of Mexico. Blackfish Goliath often gather in shipwrecks and reefs to eat and socialize.
