  2. Pharyngeal arch - Wikipedia

    en.wikipedia.org/wiki/Pharyngeal_arch

    The pharyngeal arches, also known as visceral arches, are transient structures seen in the embryonic development of humans and other vertebrates, that are recognisable precursors for many structures. [1] In fish, the arches support the gills and are known as the branchial arches, or gill arches.

  3. Branchial arch - Wikipedia

    en.wikipedia.org/wiki/Branchial_arch

    Gill arches supporting the gills in a pike. Branchial arches or gill arches are a series of paired bony/cartilaginous "loops" behind the throat (pharyngeal cavity) of fish, which support the fish gills. As chordates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa.

  4. Fish anatomy - Wikipedia

    en.wikipedia.org/wiki/Fish_anatomy

    An arch extending from the top of the centrum is called a neural arch, while the haemal arch or chevron is found underneath the centrum in the caudal vertebrae of fish. The centrum of a fish is usually concave at each end (amphicoelous), which limits the motion of the fish.

  5. Special visceral efferent fibers - Wikipedia

    en.wikipedia.org/wiki/Special_visceral_efferent...

    Special visceral efferent fibers (SVE) are the efferent nerve fibers that provide motor innervation to the muscles of the pharyngeal arches in humans, and the branchial arches in fish. [ 1 ] Some sources prefer the term "branchiomotor" [ 2 ] or "branchial efferent".

  6. Gill slit - Wikipedia

    en.wikipedia.org/wiki/Gill_slit

    Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a single outer cover. Such gills are characteristic of cartilaginous fish such as sharks and rays, as well as deep-branching vertebrates such as lampreys. In contrast, bony fishes have a single outer bony gill covering called an operculum.

  7. Fish jaw - Wikipedia

    en.wikipedia.org/wiki/Fish_jaw

    Fish jaws, like vertebrates in general, normally show bilateral symmetry. An exception occurs with the parasitic scale-eating cichlid Perissodus microlepis. The jaws of this fish occur in two distinct morphological forms. One morph has its jaw twisted to the left, allowing it to eat scales more readily on its victim's right flank.

  9. Rio Grande sucker - Wikipedia

    en.wikipedia.org/wiki/Rio_Grande_Sucker

    Fishes, amphibians, reptiles, birds, and mammals fall under the Phylum Chordata which have common morphological characteristics consisting of a notochord, nerve cord, visceral clefts, and arches. [8] Belonging to Class Actinopterygii, or ray-finned fishes, which are the most common and prosperous freshwater and marine fishes. [9]
