Orthopristis chrysoptera, the pigfish, hogfish, piggy perch, redmouth grunt or sailor's choice, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is found in the western Atlantic Ocean. This name derives from the grunting or chattering noise these fish make by rubbing their pharyngeal teeth together.
The fish can be found in or next to riffle areas in warm water, medium sized creeks and small rivers. It can also occur in cold water streams, tiny creeks and large rivers and on occasion in reservoirs. Its diet mainly consists of insect larvae, crustaceans, mollusks, diatoms, and bits of vegetation.

They get their common name because East Coast fishermen would feed these so-called "trash" fish to their hogs, after which the fish would bow its body into a suction cup and stick to the soft palate of the hog ...
Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
While the adults feed on such prey as molluscs (snails, mussels, and squid), [2] crustaceans (Mysis and brine shrimp), [2] echinoderms (brittle stars and sea urchins), worms, and small fish, [2] the juveniles act as cleaner fishes. This species can reach a length of 40 cm (16 in), though most do not exceed 28 cm (11 in).
