Ultrastructural Studies on the Ultimobranchial Bodies of Freshwater Turtle Lissemys punctata Granulosa

In the background that there is scanty literature on the ultrastructure of ultimobranchial bodies of the fresh-water turtles, this paper describes the ultrastructure of the gland of freshwater turtle Lissemys punctata granulosa . The gland was dissected out and subjected to transmission electron microscopic analysis to examine the structure of the gland. The gland is composed of a single type of cells with a few secretory granules of similar size, large cytoplasmic bodies, Golgi region, and fewer mitochondria.
