  2. Mantle (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Mantle_(mollusc)

    The mantle cavity is a central feature of molluscan biology. This cavity is formed by the mantle skirt, a double fold of mantle which encloses a water space. This space contains the mollusk's gills, anus, osphradium, nephridiopores, and gonopores. The mantle cavity functions as a respiratory chamber in most mollusks. In bivalves it is usually ...

  3. Chiton - Wikipedia

    en.wikipedia.org/wiki/Chiton

    From this ring, nerves branch forwards to innervate the mouth and subradula, while two pairs of main nerve cords run back through the body. One pair, the pedal cords, innervate the foot, while the palliovisceral cords innervate the mantle and remaining internal organs. [18] Some species bear an array of tentacles in front of the head.

  5. Mollusc shell - Wikipedia

    en.wikipedia.org/wiki/Mollusc_shell

    The mantle is visible between the open valves. A mollusc shell is formed, repaired and maintained by a part of the anatomy called the mantle. Any injuries to or abnormal conditions of the mantle are usually reflected in the shape and form and even color of the shell.

  6. Giant clam - Wikipedia

    en.wikipedia.org/wiki/Giant_clam

    Mantle of giant clam with light-sensitive spots, which detect danger and cause the clam to close. Tridacna gigas, the giant clam, is the best-known species of the giant clam genus Tridacna. Giant clams are the largest living bivalve mollusks. Several other species of "giant clam" in the genus Tridacna are often misidentified as Tridacna gigas.

  7. Siphon (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Siphon_(mollusc)

    The siphon is part of the mantle of the mollusc, and the water flow is directed to (or from) the mantle cavity. A single siphon occurs in some gastropods. In those bivalves which have siphons, the siphons are paired. In cephalopods, there is a single siphon or funnel which is known as a hyponome.

  8. Slug - Wikipedia

    en.wikipedia.org/wiki/Slug

    Mantle: On top of the slug, behind the head, is the saddle-shaped mantle. In stylommatophoran slugs, on the right-hand side of the mantle is a respiratory opening, the pneumostome, which is easier to see when open; also on the right side at the front are the genital opening and anus. Veronicellid slugs have a mantle covering the whole dorsal ...

  9. Dentalium (genus) - Wikipedia

    en.wikipedia.org/wiki/Dentalium_(genus)

    The mantle of Dentalium species is entirely within the shell. The foot extends from the larger end of the shell, and is used to burrow through the substrate. They position their head down in the substrate, with the apical end of the shell (at the rear of the animal's body) projecting up into the water.
