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]
All vertebrate jaws, including the human jaw, evolved from early fish jaws. The appearance of the early vertebrate jaw has been described as "perhaps the most profound and radical evolutionary step in the vertebrate history". [4] [5] Fish without jaws had more difficulty surviving than fish with jaws, and most jawless fish became extinct.
Petrale sole is a right-eyed flounder with an oval body. Its upper surface is uniformly light to dark brown, and its lower surface is white, sometimes with pink traces. It has a large mouth with two rows of small, arrow-shaped teeth on the upper jaw and one row of teeth on the lower jaw.
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 wrasses have become a primary study species in fish-feeding biomechanics due to their jaw structures. The nasal and mandibular bones are connected at their posterior ends to the rigid neurocranium , and the superior and inferior articulations of the maxilla are joined to the anterior tips of these two bones, respectively, creating a loop of ...
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).
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.
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 ...
