Groupers are a type of fish that belong to the family Serranidae. They are known for their large size, round bodies, and powerful jaws that allow them to swallow whole prey. There are several synonyms for the word groupers, including rockcod, hind, and sea bass. Rockcod is a common name used for groupers that are found in rocky habitats, while hind is a term used for smaller species of groupers. Sea bass, on the other hand, is a general term used for all species of groupers that are commonly found in coastal waters. Regardless of their name, groupers are a popular catch for recreational fishermen and a prized ingredient in many cuisines around the world.
