I believe you're referring to a structure called a Radula.
Gastropods obtain food by crawling around and looking for it. When they find it, they use their radula (sharp teeth-like structures that rotate) to scrape food off of things. For example, if a gastropod finds some algae on a rock, they will use radula to scrape the algae off the rock. Gastropods do not chew they scrape things off and digest it.
other molluscs have a radula which is lost in the bivalves, they also have a reduced head and nervous system. most are also lamellibranchs (filter feeders) which is why they have lost the radula (used for rasping plant life by herbivores such as the gastropods).
Some animals with a radula include snails, slugs, and certain types of mollusks like chitons and some species of squid and octopus. These animals use their radula, which is a specialized feeding structure with tiny teeth, to scrape and shred food.
radula. The radula is a tongue-like organ equipped with rows of small, chitinous teeth that are used to scrape or rasp food particles off surfaces. It is primarily found in gastropods such as snails and slugs, but is also present in other mollusk groups like chitons and some cephalopods.
Gastropods are animals such as snails. Some are carnivores and eat small insects like ants or aphids. Some are herbivores and eat various plants.
No. Oysters do not have a radula
A radula is a feeding organ found in most mollusks, especially in gastropods like snails and slugs. It is covered with tiny teeth and is used to scrape, cut, or drill food into smaller pieces before it is ingested by the mollusk.
No, snails are gastropods.
How do gastropods function as decomposers?
Marine Gastropods (snails, slugs) as a group cover pretty much every feeding strategy known. Many use their rough tongue (called a radula) to scrape micro algae off the surface of hard substrate. However, Gastropods can also be carnivores, herbivores, omnivores, scavengers, deposit feeders, suspension feeders and parasites. Some cone shells even hunt small fish!
