The gag grouper (Mycteroperca microlepis) is a drab, mottled-gray fish lacking the distinguishing features of other groupers. Ten- to 20-pound (5- to 10-kg) fish are common. The world record is 80 lb 6 oz (36.45 kg). The gag grouper is a bottomfeeder and is often caught by fishermen seeking bottom-dwelling species, such as snappers. They are found in areas of hard or consolidated substrate, and use structural features, such as ledges, rocks, and coral reefs ( as well as artificial reefs, such as wrecks and sunken barges) as their habitats.
