Each section has its own responsibility for the “operation” of the snail. The cerebral ganglia is divided into four sections. Instead, they have what is scientifically called cerebral ganglia. Snails do not have a spinal cord or a single brain like humans or other animals. The small scraps of food then continue to the digestive tract.ĭespite the small size of a snail and its tiny teeth, it is actually possible to hear the sound of food scraping inside the radula. ![]() Instead of chewing, the snail is practically scraping his food. Unlike humans and other animals that have jaws to chew their food, inside the snail’s mouth there are rows of microscopic teeth called the radula. The mouth is located in the bottom part of the head.

However, studies and experiments proved that the snails can respond to light and to some degree, see what’s in front of them. It is still unknown exactly how much the snail can actually see. Snails have eyes located on the tip of its top tentacles. They also have tactile receptors which mean they respond to light touch. This pair of tentacles is usually shorter than the upper pair.Īll of the tentacles are retractable which mean the snail can pull them back when he needs to or when he senses danger. The lower pair of tentacles have smelling capabilities. Two at the top of the head and two at the bottom. The tentaclesĪ land snail will usually have two pairs of tentacles. On the head you will see the mouth and 2 to 4 tentacles. The head of the snail is located on one end of its body. Snails can pick up on those trails to find other snails for mating purposes. You can usually see the mucus as it dries because it becomes a sort of a shiny trail. Video can’t be loaded because JavaScript is disabled: EXPERIMENT Snail on Razor! () That mucus has many amazing abilities that allows a snail to move completely vertically without falling and even crawl over a sharp blade without damaging its skin. The snail is using his muscular foot to create small wave motions of contractions and expansions in order to move around.ĭuring their glide, the snail will reduce the friction by creating mucus. The foot is basically the bottom part of the snail’s body. But they do have something that is called the foot. ![]() It is also critical in cases where the snail has a damaged shell. ![]() The consumption of calcium helps the snail to have a bigger and harder shell. Since the shell is made mostly from calcium, the snail requires a lot of calcium in its diet. They will seal the opening of the shell with some kind of mucus that will become hard and protect the delicate body temperature and humidity. Depending on the snail habitat, if it is too hot or too cold and dry, they will go inside the shell. Some species will use the shell as a protection from unsuitable weather conditions. ![]() Whenever it feels danger, the snail will retract itself into his shell. It is also the snail’s protection from predators. The main purpose of the shell is to protect the snail’s internal anatomy parts that will be explained later.
