Where does a snail get its shell from?
Snail Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Gastropoda The name snail applies to most members of the molluscan class Gastropoda that have coiled shells. Snails are found in freshwater, marine, and terrestrial environments. Most are of herbivorous nature, though a few land species and many marine species may be omnivores or carnivores. Other gastropods, which lack a conspicuous shell, are commonly called slugs, and are scattered throughout groups that primarily include snails. While most people are familiar with only terrestrial snails, the majority of snails are not terrestrial. Snails with lungs belong to the group Pulmonata, while those with gills form a paraphyletic group. Snails move like earthworms by alternating body contractions with stretching, with a proverbially low speed (1 mm/s is a typical speed for adult helix lucorum [1]). They produce mucus in order to aid locomotion by reducing friction. The mucus also reduces the snail’s risk of injury (s
