Snails include the kind served in
restaurants, as well as clams, and the snails in your garden that destroy your
plants.
They are triploblastic protostomes.
This means that their bodies are made up of a mass of material that holds the
organs, a foot that holds the muscle enabling them to attach to a surface, and
the head. Some, but not all, have eyes and tentacles.
The snail's body has a sheet or mantel, which forms a shell from secretions.
They scrape up their food by moving back and forth on an edible
surface. You can picture this when you recall seeing a snail attached to
a leaf. Later you see the leaf is full of holes. snails do not have segmented bodies, like most all land animals.
They are believed to be related to the annelids. Annelids are animals that do have segmented bodies.
They are not male or female - they are hermaphrodites. They can produce both sperm and eggs.
The snail has no sense of hearing, they use their sense of smell and feeling to maneuver about the earth.
A snail is not in the insect family. There are more snails than insects on earth.
The trail of slime that they leave as they move allows them to move on any type of surface in any terrain without being injured. Think of being able to walk on glass, sharp rocks etc. without hurting your feet.
