Snails are small soft-bodied mollusks that move very slowly on a muscular foot. They live in moist environments and are often found in gardens and fields. Snails are hermaphrodites meaning that they have both male and female reproductive organs. They lay eggs in a spiral shape and the young hatch from these eggs as miniature adults.
Snails are often considered pests because they eat plants and can carry diseases. Some people also find them to be slimy and disgusting. However snails are an important part of the ecosystem and many animals depend on them for food.
There are many different types of snails and they come in a variety of colors and sizes. The largest snail on record was a giant African snail that weighed nearly two pounds (0.9 kilograms). The smallest snail is the pygmy snail which is only about one millimeter long.
Snails have been around for a very long time. Fossils of snails have been found that date back to the early days of the dinosaurs.
