Slugs & Snails

A:

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.

  • How are snails born?

    Q: How are snails born?

    A: Snails are born out of white/yellow eggs from their mother or father, as snails are hermaphrodites, and hatch approximately 2 or 4 weeks after being laid. For the baby snails to hatch, the weather has to be the perfect mix of warm and damp weather.

  • What is the difference between a snail vs. a slug?

    Q: What is the difference between a snail vs. a slug?

    A: 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.

  • How do snails breathe?

    Q: How do snails breathe?

    A: Snails can be divided into two categories when discussing manners of breathing: those with lungs and those with gills. Pulmonate (lung) snails assimilate oxygen through the thin wall ("lung") of their mantel cavity. Other snails breathe using gills.

  • How do arthropods move?

    Q: How do arthropods move?

    A: Most arthropods move through their segmental appendages. Their exoskeleton and muscles, which are connected to the inside of the skeleton, act together as a lever system, according to Encyclopedia Brittanica. The exoskeleton provides a large surface area for muscle attachment, supports movement and provides protection from the environment.

  • Where do snails come from?

    Q: Where do snails come from?

    A: Fossil evidence dating back 550 million years identifies snail-like mollusks inhabiting the sea floor. Several million years later, snails adapted to land, breathing with lungs rather than gills. Snails now live in wide-ranging habitats from deserts to tropical climates, at sea level and in mountainous regions.

  • Q: What is the function of the mantle in mollusks?

    A: There are numerous functions of the mantle in mollusks, with the primary function being to enclose and protect the internal organs. The mantle leaves room in the mollusks body for the mantle cavity, which holds air or water and serves as a method for respiration. Mantles in mollusks also provide a way for them to communicate with one another because of the bright colors.

  • Q: Is a snail a bug?

    A: 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.

  • What do snails eat and drink?

    Q: What do snails eat and drink?

    A: A snail's diet varies according to its natural habitat. A land snail is usually herbivorous and feeds on a variety of vegetables, fruits and soft barks. Other species of snails, such as the wolf snail, are carnivores and may even eat herbivorous snails. Snails, like other living things, need water to survive but can do with just a little amount of water.
