Garden Snail
Garden snails belong to the Helicidae family. They are one of the slowest animals in the world. This species may be the most well-known of all terrestrial mollusks. For over two centuries, it was classed as Helix aspersa, but the current taxonomy places it in the genus Cornu.
In some countries, the snail is considered a delicacy, but it is also frequently recognized as a problem in gardens and agriculture, particularly in areas where it was accidentally introduced and where snails are not usually considered a menu item.
It's tough to walk rapidly when you only have one foot. The typical garden snail has a flat, muscular organ that moves it along its intended path rather slowly. According to the Dudley Zoo, the snail emits a stream of mucus to help it travel by reducing friction. That's why a garden snail's trail is usually covered in slime. The top speed of a garden snail is 1.3 cm per second, but it can travel as slowly as 1/10 of an inch (28 centimeters).
