Sweet, buttery white flesh once spines are safely removed; increasingly promoted as a sustainable food source in Atlantic waters where it is an invasive species.
Species Overview
Goliath Grouper
The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.
Red Lionfish
The red lionfish is a venomous coral reef fish native to the Indo-Pacific. Its ornate, striped body and fan-like pectoral fins make it popular in aquariums, but it has become a destructive invasive species in the western Atlantic and Caribbean.
