Interesting about the snail

  • Snails or gastropods are skeletal molluscs and comprise an estimated 100,000 different species worldwide, with a distinction between nude and snail slugs.
  • Slug snails have a spiral, pointed or round lime house they always carry with them, which serves as a shelter and shelter and can be repaired after damage. Snails retreat into their housing, which they seal with a lime cover, to survive certain weather conditions. Snails rely on shelter in the ground, in the sand or in hiding places.
  • Depending on the species, snails from a few millimeters to over half a meter in size.
  • Snails occur on all continents and colonize different habitats such as meadows, forests, gardens and parks. Aquatic snails are found both in different inland waters and in the oceans. The marine species are found in shallow waters near the coast as well as in the deep sea.
  • Snails move through a rhythmic contraction of the muscles and resulting waves, whereby they move forward on wet ground the fastest.
  • On the underside of their body, they produce a slimy secretion that protects them from rough surfaces and allows them to crawl over sharp objects. The slime of some snails is so tough and thick that they can not be injured by razors. Other species can crawl over the water surface.
  • Snails have two pairs of different sized probes that help them find their way. At the ends of the longer antennae sit the eyes, the shorter serve the sense of touch and smell.
  • As hybrids, snails propagate by nesting their bodies and laying eggs in a sheltered pit after mating. Immediately after hatching, young snails go in search of food.
  • On land snails avoid strong sunlight to protect against dehydration. In the warm season, they are therefore mainly twilight and nocturnal, in rainy periods they come out of their hiding during the day and go in search of food.
  • The European snails feed mainly on different plants. The delicate leaves, flowers and grasses grind them with the help of small teeth sitting on a rasp tongue, the so-called Radula.
  • Within the snail family there are also toothless species that feed on carrion and meat or kill their prey with small poisonous teeth used like harpoons. Other predatory snails keep following their victims until they give up. Marine species eat not only plants but also other snails, small fish or jellyfish.
  • Only a few types of snails are considered hated and intensively combated beneficial pests that destroy garden plants or decimate crops. Most gardening species are useful inhabitants of the earth, who, as waste recyclers, eat dead plant parts and the clutches of other pests.
  • Snails serve as an important food source for many species of animals. Land-living species are eaten by birds, amphibians and small mammals, aquatic snails of various fish and marine mammals. Few species are also considered a delicacy for humans.
