– Many snails are in danger of extinction. – The size of the shell of a snail reflects its age. – A single garden snail ( Helix aspersa) can have up to 430 hatchlings after a year. – The food of land snails goes through a mouth structure called the radula, which has several rows of tiny teeth inside. Even humans who eat poorly cooked snails can become seriously ill. – Snails host several types of parasites that, while may not kill them, they are capable of affecting or killing their predators or animals that eat the snails. – Calcium carbonate is the main component of the snail shells. – Some predators of terrestrial snails are beetles, rats, mice, turtles, salamanders and some birds. – Snails do not change shells when they grow up.” Instead, the shell grows along with them. – Land snails cover the entrance of their shell with a dry mucus secretion called epiphragm, but a few do it with a structure, that in the aquatic snails, has the name of the operculum. If they moved without stopping, it would take more than a week to complete 1 kilometer. – The speed of snails is around 0.5-0.8 inches per second. – Most snail species are hermaphrodites, so they have both male and female reproductive organs. – The mucus of the garden snail is used to treat wrinkles, spots, and scars on the skin. – In some places, people eat snail eggs, and call them “white caviar.” – The courtship, process by which they attract each other before mating, lasts between 2 and 12 hours. – In France, edible snails are “escargot,” a word that also applies to a dish made with them, which is an appetizer. – Most snails live from 2 to 5 years, but in captivity, some have exceeded 10 or 15 years of age. – The snails that just hatch the egg can eat their shells and even other eggs of their brothers. – North America has about 500 native species of land snails. – Some land snails feed on other terrestrial snails.” – The largest land snail is the Achatina achatina, the Giant African Snail. – When they feel threatened, they usually retreat into their shell to protect themselves. – Snails are gastropod mollusks members of the phylum Mollusca and the class Gastropoda.
