Other snails, like the generalist herbivore Arianta arbustorum, or copse snail, choose their meals based on availability, consuming a mix of arthropods, wilted flowers, fresh and decayed plant material, and soil.
The anatomy of a common air-breathing land snail: much of this anatomy does not apply to gastropods in other clades or groups. Snails are distinguished by an anatomical process known as torsion, where the visceral mass of the animal rotates 180° to one side during development, such that the anus is situated more or less above the head. This ...
Molluscs are second only to arthropods in numbers of living animal species [20] — far behind the arthropods' 1,113,000 but well ahead of chordates' 52,000. [18]: Front endpaper About 200,000 living species in total are estimated, [ 3 ] [ 24 ] and 70,000 fossil species, [ 17 ] although the total number of mollusc species ever to have existed ...
Arthropod eyes Head of a wasp with three ocelli (center), and compound eyes at the left and right. Most arthropods have sophisticated visual systems that include one or more usually both of compound eyes and pigment-cup ocelli ("little eyes"). In most cases, ocelli are only capable of detecting the direction from which light is coming, using ...
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g.octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and, vertebrates such as fish, birds and mammals.

The dye substance is a milky mucous secretion from the hypobranchial gland of one of three species of medium-sized predatory sea snails that occur in the eastern Mediterranean Sea: Bolinus brandaris, the spiny dye-murex; the banded dye-murex Hexaplex trunculus; and the rock-snail Stramonita haemastoma.
Malacology [a] is the branch of invertebrate zoology that deals with the study of the Mollusca (molluscs or mollusks), the second-largest phylum of animals in terms of described species [1] after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells.
These land snails have opercula, which helps identify them as "winkles gone ashore", in other words, snails within the clade Littorinimorpha and the informal group Architaenioglossa. Members of the snail family Pulmonata , which includes carboniferous land sails and some freshwater snails of the order Basommatophora , are protandrous ...
