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.
Bristlemouth specimen showing jaw length. Brislemouths feed mostly on zooplankton and small crustaceans. Their diet is composed of a range from 92 to 98% of Crustacea. [3] A minor part of their diet is made up of opportunistic encounters with smaller fish.
The sling-jaw wrasse's most notable feature is that the mouth of this species is armed with highly protrusible jaws which unfold into a tube which is easily half its head length (see below). [2] The males of this species are greyish-brown with orange on the back, a yellowish transverse bar on the flank and a pale grey head which is marked with ...
Lasiognathus, the wolftrap anglerfish, is a genus of deep-sea anglerfish in the family Thaumatichthyidae, with six species known from the Atlantic and Pacific Oceans.. Like its sister genus Thaumatichthys, it is distinct from other anglerfish for an enormous upper jaw with premaxillaries that can be folded down to enclose the much shorter lower jaw. [1]
Monognathus, or onejaw, is the only genus of the family Monognathidae of deep-sea eels.The name comes from the Greek monos meaning "one" and gnathos meaning "jaw", a reference to the large mouth in comparison with the rest of the fish, and also the absence of an upper jaw (maxilla and premaxilla bones are absent).
Archosargus probatocephalus is an omnivore, the larger juveniles and adults are predators of blue crab (Callinectes sapidus), oysters, clams, crustaceans, and small fish with the young Atlantic croakers (Micropogonias undulatus) The large flattened teeth are used to crush prey protected by shells or armor as well as to scrape barnacles off ...
Most species have an extended lower jaw, at least as juveniles, though this feature may be lost as the fish mature, as with Chriodorus, for example. [5] As is typical for surface dwelling, open water fish, most species are silvery, darker above and lighter below, an example of countershading. The tip of the lower jaw is bright red or orange in ...
