(3) Mesostoina tctnn/onuin (5-8 mm. long and 1-2 mm. broad) feeds upon small oligochaetes, crustaceans and insect larvae, which are captured directly by the flatworm wrapping itself around them. The bulbous pharynx is then protruded through the median ventral mouth (Fig. 3) and applied to the prey's body wall. Strong sucking movements made by alternate contractions and expansions of the radial musculature of the pharynx draw small prey bodily into the gut (Fig. 8). Larger animals are held until the body wall ruptures and the pharynx can be thrust into the body to suck out the contents, but in a somewhat inefficient manner so that frequently only the body fluids are withdrawn. Mesostouia is also a.
