The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus.

Radula is the name of the rasp like tongue which most molluscs except the lamellibranchs possess. 3-n Ampullaria and a few other genera many structural details of the radula can be seen with an x8 hand lens, but for the greater part of the molluscan genera a …

Jan 1, 2011 · The radula of S. canarium is typically of taenioglossate type with one median tooth flanked by one pair of lateral tooth and two pairs of marginals on each side (7 teeth per row).

Nov 7, 2008 · Animals in the ocean do not have the luxury of someone shucking their prey, but rather use an adaptation called a radula. A radula is the sharp, drill-like tongue of some mollusks (e.g., whelk or conch). Radulas are found on every class of mollusk except for bivalves.

The radula has been recogonised as an important morphological criterion for the taxonomic allocation of species. The radula in general vary within a subclass that of prosobranch gastropods. The scanning Electron microscope (SEM) is one of the powerful tool in the studies of radula.

Apr 18, 2024 · What is the feeding process of conch like? The **conch uses its radula to scrape and rasp the food**. The radula is covered with thousands of tiny teeth that help in breaking down plant materials or capturing small organisms.

Nov 20, 2011 · Light microscope and SEM preparations have been made of the radula of Acteon tornatilis (Linnaeus) (Opisthobranchia: Cephalaspidea). The minute teeth are illustrated with SEM photographs, the first time they have been accurately depicted.

RADULA: a ribbon of minute teeth (denticles) used for feeding. The radula is unique to molluscs and is found in all Classes except bivalves. Radula morphologies are unique to species – they are a useful diagnostic feature for identification although sophisticated techniques are required to extract and examine the radula.

In this study, five basic types of radula (i.e., docoglossan, rhipidoglossan, taenioglossan, stenoglossan, and toxoglossan), which were observed from a total of 23 different species belonging to...

The whelk has a gland that secretes a chemical that softens calcium carbonate so the radula can efficiently be used to bore a hole in the shell of the prey. When the drilling process is completed, the whelk extends its proboscis into the prey and begins feeding.
