Diet varies over the life cycle: in hatchling snails, oophagy during the hatching period inside the hollow in which the clutch was laid has been reported, significantly enhancing growth and survivorship (Desbuquois and Madec, 1998); after a few days, this behaviour is lost. Cornu aspersum (syn. Slugs are slimy, soft-bodied animals, described as shell-less snails. After two weeks the eggs hatch. Slugs are legless, unsegmented and boneless. They love moist, rotting vegetation. Common garden snails usually get from hatching to adult in about a year, occasionally faster. Diet varies over the life cycle: in hatchling snails, oophagy during the hatching period inside the hollow in which the clutch was laid has been reported, significantly enhancing growth and survivorship (Desbuquois and Madec, 1998); after a few days, this behaviour is lost. The process of egg-laying begins shortly after mating and the entire life cycle repeats again. Snails are known to be one of the oldest animals living on the planet. This is a less straightforward question than it seems. Brown garden snails attain a diameter of 16 to 20 mm within one year, and 26 to 33 mm by the second year. The parasite only gets passed on to humans when people eat uncooked snail meat. After mating they lay around 80 white eggs in a damp, underground nest. The head region of a slug has two pairs of retractable tentacles, with one pair bearing eye spots. The snails inseminate each other and bury the up to 100 eggs in warm and damp soil between 5 and 10 cm below the surface. Born and develop. These snails are nocturnal and feed on organic matter in the soil, tree bark, and vegetation. Female snails will give birth to live, crawling young from June to October. Eggs are deposited in a nest below the soil. Snails are proficient hitchhikers, moving between regions on transport. Fossil evidence of primitive gastropods highlights the fact that these creatures have been surviving for 500 million years. There are several kinds of snails but are mostly classified based on their habitat – terrestrial and aquatic snails. The brown garden snail is common in cool, moist areas of the world. Snails are gastropod animals which have an enclosing shell, into which it is able to retract entirely, for protection. The brown garden snail lays about 80 spherical shaped white or yellowish colored eggs at a time into the topsoil of the ground. Slugs feed on leaves of many plants (especially seedlings), ripening fruits and vegetables, and decaying plant matter.
