Snail bears a univalve (one-piece) shell.A typical snail shell is cone-shaped
and spirally coiled.There are thousands of species of snails,no two species
having shells of exactly the same shape or color.Some shells are drab,
varying from gray to brown; others are brightly colored with orange,red,and yellow designs.
Snails move at an incredible slow speed.An average adult moves at a speed of 1 millimeter per second.While moving,snails leave behind a trail of slime,a lubricant they produce to allow them to easily move across any type of terrain without injuring its body.
