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.
Most fish species with pharyngeal teeth do not have extendable pharyngeal jaws. A particularly notable exception is the highly mobile pharyngeal jaw of the moray eels.These are possibly a response to their inability to swallow as other fishes do by creating a negative pressure in the mouth, perhaps induced by their restricted environmental niche (burrows) or in the air in the intertidal zone.

Parrotfishes are most known for their beak jaws that are fused together with their teeth. Their distinct teeth allow them to crush and grind food. [4] The pharyngeal jaw is the second set of teeth located in the throat. [5] The color of the princess parrotfish (Scarus taeniopterus) depends on their gender. Males have a blue body with yellow ...
These fish are edentulous, lacking teeth on their jaws; however, they do have pharyngeal teeth in their throat. [2] Their eyes are nearly atop their heads pointing upward. [ 4 ] They have a slightly compressed body with the deepest part by the back of their neck. [ 4 ]
The pharyngeal jaws, so-called because they are positioned within the pharynx, are used to further process the food and move it from the mouth to the stomach. [2] [3] Cartilaginous fishes, such as sharks and rays, have one set of oral jaws made mainly of cartilage. They do not have pharyngeal jaws.
The branchial system is typically used for respiration and/or feeding. Many fish have modified posterior gill arches into pharyngeal jaws, often equipped with specialized pharyngeal teeth for handling particular prey items (long, sharp teeth in carnivorous moray eels compared to broad, crushing teeth in durophagous black carp).
Packed full of color, character, and intrigue, these easy-to-look-after under-the-water creatures still require all the basic usual fish care — like the best fish food, a strict cleaning ...
The mouth cone ("everted pharynx") of a possible new species of Meiopriapulus, a marine worm in the Priapulida, bears pharyngeal teeth. [5] Fossils of the Yunnanozoon and Haikouella possess pharyngeal teeth. The lower pharyngeal bones of cichlids also carry specialized teeth which augment their normal mandibular teeth in the breakdown of food.
