The upper jaw, or maxilla [12] [13] is a fusion of two bones along the palatal fissure that form the upper jaw. This is similar to the mandible (lower jaw), which is also a fusion of two halves at the mandibular symphysis. In bony fish, the maxilla is called the "upper maxilla," with the mandible being the "lower maxilla".
Physically similar to blennies, most jawfish species are small fish (up to 10 cm or 3.9 in) with an elongated body plan. A few species, for example the aptly named giant jawfish (O. rhomaleus), reaches about 0.5 m (1 ft 8 in). Their heads, mouths, and eyes are large in size relative to the rest of their bodies.
Pharyngeal teeth are teeth in the pharyngeal arch of the throat of cyprinids, suckers, and a number of other fish species otherwise lacking teeth. [ 1 ] Many popular aquarium fish such as goldfish and loaches have these structures.

Osteichthyes (bone-fish) or bony fishes are a taxonomic group of fish that have bone, as opposed to cartilaginous skeletons. The vast majority of fish are osteichthyans, which is an extremely diverse and abundant group consisting of 45 orders, with over 435 families and 28,000 species. [21] It is the largest class of vertebrates in existence today.
The Syngnathidae is a family of fish which includes seahorses, pipefishes, and seadragons (Phycodurus and Phyllopteryx). The name is derived from Ancient Greek: σύν (syn), meaning "together", and γνάθος (gnathos), meaning "jaw". [1] The fused jaw is one of the traits that the entire family have in common. [2]
The upper portion of the second embryonic arch supporting the gill became the hyomandibular bone of jawed fishes, which supports the skull and therefore links the jaw to the cranium. [ 4 ] When vertebrates found their way onto land, the hyomandibula, with its location near the ear, began to function as a sound amplifier beside its function to ...
The small terminal mouths of filefish have specialized incisor teeth on the upper and lower jaw. In the upper jaw there are four teeth in the inner series and six in the outer series. In the lower jaw, there are four to six in an outer series only. The snout is tapered and projecting and the eyes are located high on the head.
