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.
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.
Squids share two traits with other mollusks: a soft body typically covered by a mantle and a foot modified into tentacles. Additionally, both squids and other mollusks possess a radula, a feeding organ used for scraping food.
Squids do not have legs. They have tentacles that are used for capturing prey. Baby squids, known as squid larvae, hatch with small tentacles that continue to develop as they grow.
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.
The function of these openings is to excrete waste from the earthworms body.

A radula is a feeding organ found in mollusks, such as snails and slugs. It is covered in tiny, chitinous teeth that are used to scrape, shred, or drill food before ingestion into the mouth. The radula's function is to help in the processing of food particles for digestion.
Squid are cephalopods, a marine animal that has bilateral body symmetry and a unique head. The function of a squids liver is to absorb digested food.
The function squid testis is to produce sperm during reproduction.
No. Oysters do not have a radula

The radula (or some form of the radula) is found in all classes of mollusks except bivalves (organisms with two shells such as clams).
