speeds of snails and slugs

• The speed of a common snail is about 1 millimeter per second, or 0.002 mph
• slugs travel at speeds that vary from slow (0.013 m/s) to very slow (0.0028 m/s).

Some snail species are faster than some slug species, and some snails do not move at all, they stay put at the bottom of the sea and feed on any plankton that may drift their way.
