Interesting facts about snails

Many people don’t even notice these little creatures, snails, whose slowness has become a proverb. They have been living on Earth for a long time, and for millions of years evolution has hardly changed them - apparently, Mother Nature believes that they are already well adapted to survive. It is difficult to argue with this, as snails have been living on our planet much longer than humans, and, judging by all appearances, successfully. And in some countries, they are even a delicacy, and are actively used in local cooking.

Facts about snails

  • Snails have the honor of becoming the first real cyborgs - a group of scientists in the experiment's course transferred neurons of the experimental animals on a computer chip.
  • Both salt and sugar are very poisonous to snails.
  • Snails contain more proteins than chicken eggs.
  • The English have traditionally had such a folk sport as speed snail races. In order to make them crawl where they need to, they “draw” paths with lettuce leaves on the table in front of them.
  • The nervous system of snails contains only about 20,000 neurons. The human brain, for example, has billions of neurons.
  • The average speed of movement of a snail does not exceed 6-7 centimeters per minute.
  • Snails of the same species can have significantly different shell colors - it depends on the menu of these creatures, as well as on other living conditions.

  • Usually snails do not drink water but simply absorb it with the entire surface of their body.
  • These creatures are strong for their size. They can easily bear 8-10 times their own weight.
  • The snail’s funny horns are its olfactory organs. In fact, they are a nose turned inside out.
  • Most snail species are hermaphroditic and do not need a mate to reproduce.
  • All snail species are deaf. They simply do not have hearing organs.
  • Australia is home to giant sea snails, which, with a shell length of up to half a meter, can weigh over 15-17 kg, making them one of the largest mollusks in the world.
  • Snails have very poor eyesight. They can only distinguish between light and shadow. However, they have a very keen sense of smell, and at a distance of a couple of meters, they can easily detect food.
  • To communicate with their congeners, snails touch each other.
  • Snails are the species with the largest number of teeth on our planet. They have about 25,000 of them! True, all their teeth are so small that it is necessary to examine them under a microscope.
  • These creatures can not chew, so they just grind particles of food to mush.
  • The more calcium in the snail’s diet, the stronger its shell is.

  • The shell of a snail is almost always twisted in a clockwise direction. Individuals with a shell twisted counterclockwise are extremely rare.
  • To facilitate its movement, the snail creates a kind of cushion of slime between its sole and the surface, and crawls on it.
  • Many species of snails live 14-15 years, which can be compared to the life span of such animals as the lynx or the tiger.
  • Even quite large snails can easily crawl on a sharp knife blade without hurting themselves.
  • In case of cold weather, they may hibernate for a long time, for up to 5-6 months. In hibernation, the snails may successfully survive temperatures as low as -100 degrees Celsius or higher.
  • During experiments, scientists found snails learn, assimilate experiences and put them into practice, showing they have certain intelligence.
  • They can hide entirely in their own shell in case of danger.
  • Charles Darwin, the creator of the theory of evolution, cited snails as an example of a life form capable of adapting to almost any conditions.
  • The first snails appeared on earth about 600 million years ago, long before most dinosaurs ever roamed our planet.
  • Snails can’t tolerate caffeine - it’s 0.01% content discourages them from eating food, and a 1% solution can kill them altogether.
  • The muscle designed to hide the snail inside the shell covers its whole body.
  • Snails are not vegetarians. They willingly include in their diet various larvae and worms.
