. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. 120 J. B. JENNINGS devices. The mucus produced during locomotion quickly dries out and plays no part in the capture of food, unlike that of some aquatic triclads which persists about the habitat as sticky strands to entangle insect larvae and crustaceans. The prey appears to be found by chance and starved individuals show no awareness of the proximity of either damaged or intact animals until random movements bring them into direct contact. When an appropriately sized slug or earthworm is encountered the flatworm rapidly extends across the width of the prey until it can grip the substratum on each side and so pin the captured animal beneath the arched body. The grip on both prey and substratum is helped by copious secretions of mucus from the ventral surface and is so effective that prey rarely escape. Movement across the prey continues until the mouth, which lies ventrally approximately one-third of the body length from the posterior end, can lie brought into contact with it. The muscular tubular pharynx is then protruded through the mouth and after moving rapidly over the surface of the prey is eventually thrust through the body wall (Fig. 1). When this occurs the flatworm changes position slightly to bring the mouth directly over the point of penetration to enable the pharynx to extend as fully as possible into the prey. The precise means of penetration could not be.
