Carnivory in some taxa may simply involve grazing on colonial animals, while others engage in hunting their prey. Cephalopods have suckers on their tentacles with which to grab onto their prey. How long do gastropods live? Most terrestrial gastropods eat plants, both living and decaying. The radula is used in feeding: muscles extrude the radula from the mouth, spread it out, and then slide it over the supporting odontophore, carrying particles or pieces of food and debris into the esophagus. How long does it take the gastropods egg to hatch? They include grazers, browsers, suspension feeders, scavengers, detritivores, and carnivores. As the marginals swing inward, food particles are carried toward the midline of the radula and collected into a mucous mass. Primitively, the pulmonate radular tooth has three raised points, or cusps (i.e., is tricuspid), but modifications involving splitting of cusps or reductions to one cusp are numerous. In terms of feeding, opisthobranchs are extremely varied. They then have what is known as a radula, otherwise known as a rasp tongue, with which they rasp their food into pieces so they can easily swallow it. © 2016 Just Gotta Dive (JGD), All Rights Reserved. 19.  Some are carnivorous and others eat only plant material.

Marine gastropods include herbivores, detritus feeders, carnivores and a few ciliary feeders, in which the radula is reduced or absent. They are able to withdraw all soft parts into the shell for protection, sometimes being able to seal the shell opening with a hardened disc or clamping down onto a rock for protection using the foot as a holdfast. Radular morphology is an important tool for species identification. Most terrestrial gastropods eat plants, both living and decaying.

Predators capable of swimming, surface crawling, and burrowing to capture prey have evolved among the prosobranchs and opisthobranchs; predators that produce chemical substances for entering the shells of their prey have evolved among the mesogastropods (family Naticidae and superfamily Tonnacea), the neogastropods (family Muricidae), and a nudibranch opisthobranch (Okadaia); and, in the pulmonates, predation and thus a carnivorous diet have evolved at least 12 times. Some gastropods, for example, possess a “toxoglossate” radula that has only two teeth, which are formed and used alternately. Although many cones hunt polychaete worms, others prey on gastropods or fishes, using the radular tooth as a harpoon, with poison being injected into the prey through the hollow shaft of the tooth. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. gastropoda characteristics. Gastropods. Explain what this means.

The herbivorous snails devour a wide variety of live plant parts: leaves, stems, plant crops, bark, and fruits.

Gastropod feeding habits are extremely varied, although most species make use of a radula in some aspect of their feeding behavior. Although attached at both ends, the radula grows continuously during the gastropod’s life, with new rows of denticles being formed posteriorly to replace the worn denticles cast off at the anterior end. Some species of the order Archaeogastropoda still retain the basic rhipidoglossan radula, in which many slender marginal teeth are arranged in transverse rows. 21.
