A radula is a tongue-like organ located in the mouth of a mollusk. It has rows of backward curving teeth that grasp prey.
No, a radula is not a foot. It is a tongue-like organ found in most mollusks, such as snails and slugs, that is used for feeding by scraping food particles. The foot of a mollusk is a muscular organ used for movement.
The tongue-like organ in mollusks that works like a file is called a radula. It is a flexible band covered with rows of tiny teeth that helps the mollusk to scrape and shred food before ingesting it. The radula is characteristic of mollusks and is used for feeding in species like snails and slugs.
The oyster borer is adapted to bore through the hard shell of oysters using its specialized shell-crushing radula. It secretes an acid to soften the shell and has a muscular foot that helps it bore into the oyster. The oyster borer also has a tube-like body shape that allows it to navigate within the oyster shell.
Ammonites were marine animals that likely fed on small fish, plankton, and other small marine creatures. The shape of their jaws and radula suggest a diet of soft-bodied organisms.
Yes. So long as the function has a value at the points in question, the function is considered defined.
The purpose of the radula of a squid or a snail is similar to that of a tooth. It is part of the equivalent of the tongue, and abrades hard bits from their prey.
No. Oysters do not have a radula

A squid's radula is a feeding organ that helps scrape or rasp food particles and bring them into the mouth. It is covered in tiny teeth-like structures called denticles that aid in breaking down and consuming prey.
The radula (or some form of the radula) is found in all classes of mollusks except bivalves (organisms with two shells such as clams).
One class of molluscs that lacks a radula is the Bivalvia, which includes clams, mussels, and scallops. Instead of a radula, these organisms have two shells that they use to filter feed. They do not require a radula for scraping or grazing on food sources like other molluscs.
It it used for feeding (NovaNet) :)
Yes they do
both slugs and snails use a structure called a radula to eat.
The radula is a specialized feeding organ found in many mollusks, such as snails and slugs. It resembles a ribbon-like structure covered with rows of tiny, chitinous teeth that scrape or cut food as the mollusk feeds. This organ is essential for processing food, allowing these animals to consume a variety of substances, including plant material and algae. The radula's structure and function can vary significantly among different mollusk species, reflecting their diverse diets.

Mollusks that possess a radula include gastropods (such as snails and slugs), bivalves (in some cases, like certain primitive species), and cephalopods (like squids and octopuses). The radula is a unique feeding organ that functions like a tongue, equipped with tiny teeth to scrape food from surfaces. However, many bivalves lack a radula, as they primarily filter feed. Overall, the radula is most commonly associated with gastropods and cephalopods.
