Grouper

Groupers are teleosts, typically having a stout body and a large mouth. They are not built for long-distance fast swimming. They can be quite large, and lengths over a meter and weights up to 100 kg are not uncommon, though obviously in such a large group species vary considerably. They swallow prey rather than biting pieces off it. They do not have many teeth on the edges of their jaws, but they have heavy crushing tooth plates inside the pharynx. They habitually eat fish, octopuses, and crustaceans. They lie in wait, rather than chasing in open water..
