Feeding behavior of Ampullaria canaliculata

Ampullaria canaliculata has a wide range of food habits, including animals and plants, but mainly fresh and juicy plants, especially aquatic vascular plants. Such as duckweed, water bamboo, lotus root, rice, etc. While young snails feed on algae and humus debris floating on the water surface.

In a hungry state, Ampullaria canaliculata will feed on young snails and small aquatic animals such as snail eggs, fish and shrimp, and scrape off the cuticle on the shell surface of other Ampullaria canaliculata with its powerful jaws and teeth.

Ampulla canaliculata mainly uses the tentacles on both sides of the base of the snout and the labial whiskers on the front end to find food, while the ventral foot, jaw and toothed tongue are important feeding organs of Ampulla canaliculata. When feeding, Ampullaria canaliculata will first hold the food with its abdomen and feet, and send it to its mouth around a half ring to the left.

At this time, the mandible opens, and a part of it extends out of the mouth, so that the food is quickly caught and rolled into the pharynx by contracting the pharyngeal muscle, and at the same time, the opening of the mandible is gradually narrowed and retracted. Subsequently, the tongue interacts with the lower jaw to file food, that is, to complete a meal.
