Abstract

The tongue is generally represented in all vertebrates although it varies widely in the extent to which it is developed. Among the fish it occurs in its most primitive condition. It is called a primary tongue and is merely a fleashy fold of dense connective tissue developed from the floor of the mouth between the hyoid and mandibular arches, the hyoid frequently extending into it and supporting it. It is incapable of motion except as moved by the supporting skeleton for it lacks intrinsic muscles. It is sensory, having both tactile and gustatory functions. It is often papillose, and in a few Teleosta it bears teeth, Kingsley (1926).
