Abstract

A variety of amphibian, reptilian, avian, and mammalian hosts were used in experimental development of Posthodiplostomum minimum. As a result of this study much host-induced morphological variation was noted in several organs of attachment. Variations in the oral sucker ranged from a well-developed muscular organ to a weakly developed oral slit. Acetabular development ranged from well-developed to reduced forms lacking apical musculature, tegumental spines, and sensory structures. The holdfast organ showed marked reduction in most poikilothermic hosts.
