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
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.
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 ...
Unlike some slugs, European Arionidae have no keel on the back. [1] The caudal mucous pit is above the tip of the tail. [1] The respiratory pore (pneumostome) is in front of the midpoint of the mantle. [1] The body length is up to 250 mm. [1] The mantle covers only a part of the body and lies in the anterior part. [1]
Gastropods (/ ˈ ɡ æ s t r ə p ɒ d z /), commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (/ ɡ æ s ˈ t r ɒ p ə d ə /). This class comprises snails and slugs from saltwater, freshwater, and from the land.
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.
Costasiella kuroshimae is a species of sacoglossan sea slug. Costasiella kuroshimae are shell-less marine opisthobranch gastropod mollusks in the family Costasiellidae . [ 1 ] Despite being animals, they indirectly perform photosynthesis , via kleptoplasty .
