Although mollusks are probably best
known for their unique shells, the word itself actually comes from
he Latin word for "soft." Beneath their shells, mollusks
are actually very soft-bodied invertebrates (no spine) -- and some
of the most well-known mollusks (like the octopus, for example)
have no shells at all. Mollusks share a mantle (a fold of skin that
lines the shell, when present) and a muscular foot that they use
for motion. Many types of mollusks are raised and captured for food
-- squid and clams, for example -- and some people consider eating
snails a true delicacy.

Thanks to the thick slime that they secrete, snails
can travel up completely verticle surfaces, and even upside down! |
