: Mycteroperca venenosa
The yellowfin grouper can be found in the Carribbean, the Gulf of Mexico, and off the coast of South America. Along with 449 other species in the family Serranidae this grouper is often sought by spearfishermen as well as converntional fishermen alike. Not to be confused with the yellowmouth grouper this species has a distinctive yellow coloration on the edges of the pectoral fins. The yellowfin grouper feeds mainly on fishes associated with its reef shelter but will also eat squids as well. Those planning on eating these fish should be aware that they are often associated with ciguatera poisoning. The greatest weight recorded for this fish is 40 pounds which measured nearly 40 inches.
