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.

    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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Q: Why do snails move so slowly?

    A: Snails move slowly because, as gastropods, their only method of locomotion is to use their powerful stomach muscles as a kind of foot by flexing and releasing tension in said muscles. This process is reliable but makes the snail a very slow insect without any agility or ability to maneuver quickly, weaknesses offset by their durable shells, which they use for protection.
