A typical radula comprises a number of bilaterally-symmetrical self-similar rows of teeth rooted in a radular membrane in the floor of their mouth cavity. Some species have teeth that bend with the membrane as it moves over the odontophore, whereas in other species, the teeth are firmly rooted in place, and the entire radular structure moves as one entity.
Unlike other Aeolidida, the family Aeolidiidae possesses radular teeth which aid in feeding on their prey (See Fig. 2). [7] The radula is a feature in majority of mollusks located in the mouth, like a tongue, containing thousands of teeth that help cut up food for digestion by scraping against rocks or even Fig. 2 A. papillosa Radular Teeth
Like most mollusks, these slugs have a mouth on the bottom of their head with a jaw that enables them to break off smaller bits of food. Inside their mouth, they have a tongue called a radula that is covered in microscopic teeth to help break down the food even further. Once the nutrients of the food have been broken down and absorbed, the slug ...
Yellow slugs, like the majority of other land slugs, use two pairs of tentacles on their heads to sense their environment. The upper pair, called optical tentacles, is used to sense light. The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident ...

Limax maximus (literally, "biggest slug"), known by the common names great grey slug and leopard slug, is a species of slug in the family Limacidae, the keeled slugs. [4] It is among the largest keeled slugs, Limax cinereoniger being the largest. Limax maximus is the type species of the genus Limax. The adult slug measures 10–20 cm (3.9–7.9 ...
The inset shows one individual tooth. Because of the slug's white colour and nocturnal habits, and because it is so rarely seen, it was given the species name ysbryda, the word "ysbryd" meaning ghost in the Welsh language. This in turn gave rise to the common name, "ghost slug". This appears to be the first case of a species name having been ...
