Lissamphibia
(redirected from Lissamphibian)Lissamphibia
The subclass of Amphibia including all living amphibians (frogs, toads, salamanders, and apodans). The other two subclasses are the Labyrinthodontia and the Lepospondyli. See Labyrinthodontia, Lepospondyli
Living amphibians are grouped together by possession of a unique series of characters, the most important of which are (1) pedicellate teeth, consisting of two segments, a crown and a pedicel; (2) an operculum-plectrum complex of the middle ear; (3) the papilla amphibiorum, a special sensory area of the inner ear; (4) green rods in the retina of the eye; (5) similar skin glands; and (6) a highly vascular skin used in respiration (cutaneous respiration).
