The haemulids, although known collectively as grunts, are known individually by a number of names, among them porkfish, pigfish, sweetlips, margate, and tomtate. Among the better-known species are the blue-striped, or yellow, grunt (Haemulon sciurus), a striped, blue and yellow Atlantic fish up to 46 cm (18 inches) long; the French grunt (H. flavolineatum), a yellow-striped, silvery blue Atlantic species about 30 cm (12 inches) long; the margate (H. album), a usually pearl gray species of the western Atlantic; the pigfish (Orthopristis chrysoptera), a western Atlantic food fish, striped silvery and blue and about 38 cm (15 inches) long; the porkfish (Anisotremus virginicus), a western Atlantic reef fish that, when young, is marked with black and serves as a “cleaner,” picking parasites off larger fishes; several species of sweetlips (Plectorhynchus), which are Indo-Pacific fishes, highly variable in colouring and sometimes kept in marine aquariums; and the tomtates (Bathystoma rimator and related species), grunts found off Florida and the West Indies.
