To move, snails make a complex series of wave-like movements along their entire body, which propels them forward. Most of a snail's body actually consists of a large foot, and so the part of the body touching the floor is known as the sole.Know More
As the snail moves forward, mucus comes out of a gland located at the front end of the foot, and the snail moves across this gooey substance. The mucus cuts down on the amount of friction that the ground causes for the snail, reducing contact to the point that a snail can crawl along the edge of a knife and not suffer from any cuts. Studies looking into whether the mucus is a requirement for movement are inconclusive, but the mucus clearly helps the movement go more quickly and easily.
Different snails have the ability to move at different speeds. For example, the Roman snail hits top speeds of about 2 1/2 inches per minute, while the pond snail is one of the faster species, hitting top speeds of almost 5 inches per minute. The bladder snails are a group of freshwater species that are capable of hitting speeds of up to 8 inches per minute.Learn more about Bugs
Snails do have teeth that they use to eat, so in that sense, yes, they can bite. However, snails typically do not bite humans, and if they do, their jaws may not be strong enough to make much impact. However, there are some types of snails that are dangerous to humans.Full Answer >
Snails are not insects. They are members of the class Gastropoda, and are more closely related to squid than to the insects that live in gardens.Full Answer >
Snails reproduce by inseminating each other with sperm. Once this sperm is collected, it internally fertilizes the ova. A hundred eggs may develop from a single reproductive effort.Full Answer >
Snails move slowly because, as gastropods, their only method of locomotion is to use their powerful stomach muscles as a kind of foot by flexing and releasing tension in said muscles. This process is reliable but makes the snail a very slow insect without any agility or ability to maneuver quickly, weaknesses offset by their durable shells, which they use for protection.Full Answer >
