These mollusks have fleshy, soft, slimy, legless bodies and range in color from whitish-yellow to black. They vary in size from 1/2 inch up to 4 inches. Snails are slow-moving and require moisture for survival. Snails have a hard spiral shell on their backs that provides protection from predators and during periods of excessive heat and dryness.
Snails feed on plants by scraping off the tissue or eating holes in the leaves or flowers; leave glistening trails of slime wherever they crawl.
