The Goliath or giant grouper is also known as the brindlebass. It is called the Queensland grouper in Australia. It is considered the biggest fish with a skeleton that inhabits coral reefs. It can swim to about 330 feet deep but is often found near the surface. They feast on a variety of fish that swim near the surface. Among them are young sea turtles and smaller breeds of sharks. Unfortunately, this breed of grouper has dwindled in number because of overfishing. It may be big but it is easy to catch. Here are the biggest goliath groupers ever recorded.
