The number of teeth a snail has depends on the type of snail, but the average snail has well over 1,000 teeth. The teeth of snails are contained in rows called a radula. These rows shift and allow missing teeth to be replaced.Continue Reading
Snails are voracious eaters that use their small, sharp teeth to rip through vegetation. The consistent ripping and chewing wears down the teeth and causes the radula to create a new row, pushing all of the rows forward, helping to rotate the teeth.
The radula is sometimes mistaken for a tongue. However, it is possible to hear a snail chew its food, when observed in a quiet room.Learn more about Slugs & Snails
Snail shells are formed when a snail continually feeds on calcium. A snail is born with a soft version of its shell that needs calcium to grow into the hardened form.Full Answer >
The protoconch, or first shell that a snail is born with, grows with the snail as the animal's mantle -- an organ that lines the shell -- releases new shell material that expands the shell before hardening. This shell the snail was born with becomes the center of the spiral.Full Answer >
Snails are members of the class Gastropoda, phylum Mollusca, and thus are not formally considered bugs. True bugs are part of class Hemiptera, which are from the phylum Arthropoda. Informally, however, bugs are considered to include all land invertebrates; in this sense, land snails are included.Full Answer >
The most-noticeable difference between a snail and a slug is the slug's lack of a shell. On a snail, the shell houses and protects the visceral hump, where the snail's organs are located. A slug, on the other hand, may have an internal "shell," which is more like a calcium deposit, that helps protect the internal organs.Full Answer >
