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.
Gastropods (snails and slugs) as the largest taxonomic class of the mollusca are very diverse: the group includes carnivores, herbivores, scavengers, filter feeders, and even parasites. In particular, the radula is often highly adapted to the specific diet of the various group of gastropods.
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 ...
Individual teeth are subjected to shear stresses as the tooth is dragged along the rock. Goethite as a mineral is a relatively soft iron based material, [15] which increases the chance of physical damage to the structure. Limpet teeth and the radula have also been shown to experience greater levels of damage in CO 2 acidified water.
Limax is a genus of air-breathing land slugs in the terrestrial pulmonate gastropod mollusk family Limacidae. Limax cinereoniger. The generic name Limax literally means "slug". Limax dacampi. Some species, such as the leopard slug (L. maximus) and the tawny garden slug (Limacus flavus), are beneficial for the garden. [2]
Scaphopoda / s k æ ˈ f ɒ p ə d ə / (plural scaphopods / ˈ s k æ f ə p ɒ d z /, from Ancient Greek σκᾰ́φης skáphē "boat" and πούς poús "foot"), whose members are also known as tusk shells or tooth shells, are a class of shelled marine invertebrates belonging to the phylum Mollusca with worldwide distribution and are the only class of exclusively infaunal marine molluscs.
This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca.
