  2. External gills - Wikipedia

    en.wikipedia.org/wiki/External_gills

    External gills are the gills of an animal, most typically an amphibian, that are exposed to the environment, rather than set inside the pharynx and covered by gill slits, as they are in most fishes. Instead, the respiratory organs are set on a frill of stalks protruding from the sides of an animal's head. The axolotl has three pairs of external ...

    en.wikipedia.org/wiki/Fish_gill

    The gill arches of bony fish typically have no septum, so that the gills alone project from the arch, supported by individual gill rays. Some species retain gill rakers . Though all but the most primitive bony fish lack a spiracle, the pseudobranch associated with it often remains, being located at the base of the operculum.

  4. Branchial arch - Wikipedia

    en.wikipedia.org/wiki/Branchial_arch

    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 .

    Its external gills are located near its rear. Its body is covered in papillae , fleshy protuberances used for sensory functions, giving it the appearance of a furry animal. [ 4 ] There are multiple colorations of Jorunna parva , including yellow, white, and green, though the latter is rarely photographed. [ 5 ]

    The gills of most teleost fish help to eliminate ammonia from the body, and fish live surrounded by water, but most still have a distinct bladder for storing waste fluid. The urinary bladder of teleosts is permeable to water, though this is less true for freshwater dwelling species than saltwater species.

  8. West African lungfish - Wikipedia

    en.wikipedia.org/wiki/West_African_lungfish

    In general, three external gills are inserted posterior to the gill slits and above the pectoral fins. It has cycloid scales embedded in the skin. About 40–50 scales occur between the operculum and the anus, and 36–40 around the body before the origin of the dorsal fin. It has 34–37 pairs of ribs.

    Red represents a higher value (e.g. of temperature or the partial pressure of a gas) than blue so the property being transported in the channels flows from red to blue. In fish a countercurrent flow (lower diagram) of blood and water in the gills is used to extract oxygen from the environment. [6] [7] [8] All basal vertebrates breathe with gills.
