[Jaws of fish 2].
Structure of Jaws in fish composed of mandibular and hyoid arches. Hyomandibular which is upper part of hyoid arch plays an important role of jaw suspension. Various jaw structures are developed in fish. One of the samples is protrusible upper jaw in cyprinid fish. Development of the protrusible jaw structure was related to degeneration of oral teeth and development of pharyngeal teeth in cyprinids.
