The eyes are on the longer pair. The shorter pair is used for smelling and feeling its way around. The tentacles are very important to a snail. A snail have something called a radula in its mouth for grinding up its food. This radula is like a rough tongue, something like a file with rows of tiny teeth which it uses to scrap off leaves and flowers to eat.
Many people get upset and farmers get angry when snails eat their plants and crops.
Snails can cause serious damage to crops. Snails eat mostly living plants as well as decaying plants. They also chew on fruits and young succulent plant barks. The largest known land snail named Gee Geronimo was a Giant African Snail collected in Sierra Leone in 1976. The band of muscles in the foot contract and expand and this create a kind of rippling movement that pushes the snail forward.
