A diver near a huge Grouper.

The Giant Grouper (Epinephelus lanceolatus) is a large saltwater reef fish from the family Serranidae and the genus Epinephelus. This fish lives near reefs, and especially in the shallow water of the Indo Pacific Region and Australia. Reports and catches suggest the fishes size (at the maximum) is barely 10 feet in length and 1200 pounds in weight. It will eat anything smaller than it, including reef fish, sharks and turtles.
