Nemertea
...Most nemerteans are carnivorous and predatory, catching prey with their proboscis,[4] although some are scavengers and some are herbivores.[5] In some families, it is armed with a sharp stylet which may be poisonous, while those that lack the stylet often use a sticky secretion on the proboscis to entrap their prey. The proboscis is wrapped around the prey, which is normally other invertebrates such as crustaceans and annelids and can be many times larger than the nemertean itself, and the prey is then stabbed repeatedly with the stylet until dead.[6]. A few, such as Malacobdella, live parasitically in the mantle cavity of molluscs and live on the food filtered by their hosts [6]
...A ribbon worm's food consists of segmented worms and small crustaceans which are encountered and captured by trial and error. Whenever the worm is successful in this endeavor, the proboscis coils around the prey organism, and then is retracted to bring the food to the mouth. The digestive tube is straight and non-muscular, and movement of food in it occurs mainly by ciliary action. An anus is present at the posterior end.
Ribbon Worms ...The ribbon worm is noted for its proboscis (a cordlike organ extending from the head), often several times the length of the body, which it shoots out and wraps around prey. In some, the proboscis ends in a sharp stylet, a bristlelike organ through which the worm injects venom into its prey.
