The following is a list of common fish species known to occur in the lakes and rivers of Canada.
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 ]
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.

Hemiramphidae is a family of fishes that are commonly called halfbeaks, spipe fish or spipefish. They are a geographically widespread and numerically abundant family of epipelagic fish inhabiting warm waters around the world. The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws.

Cyprinids are stomachless, or agastric, fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...
Instead, they have convergent structures called pharyngeal teeth in the throat. While other groups of fish, such as cichlids, also possess pharyngeal teeth, the cypriniformes' teeth grind against a chewing pad on the base of the skull, rather than an upper pharyngeal jaw.
