Sharks are usually at the top of the food chain, except when they are smaller than goliath grouper.
The monster fish snack on small sharks like the one in this video taken last February in Key West, Fla. An offshore angler reels in a small shark from his boat when a giant goliath grouper surfaces and gobbles it up. The fish robbery happens in just a split second, but the angler's buddy manages to capture it all on camera. Check it out.
Goliath Grouper can grow up to 10 feet in length and weigh up to 790 pounds. They typically eat sharks, juvenile sea turtles, barracudas, octopus and other fish. Anglers can find goliath grouper in coral and artificial reefs in the Florida Keys, the Bahamas, the Caribbean, the Brazilian coast and the Azores.
