Snails Rumina decollata
Is a brown garden snail, native to North Africa. Some give it an Asian, African and even Western origin. it is distinguished by a pale yellow, brown or whitish cylindrical shell, truncated in its apical part and whose size varies from 40 to 50 mm.
Mollusks in general and Rumina Decollata in particular are hermaphrodites, but mating is not obligatory in certain species. This is the case of the species cited above which is in fact characterized by its self-fertilization. it can lay up to 200 eggs, after incubation for 20 days to 1 month.
The animal becomes an adult at approximately 12 months. Like all snails during hot weather, Rumina Decollata enters a slowed life (estivation) for 6 months or more. Mortality is high during this period and increases gradually until the end of aestivation.
The species prepares for a slow life by blocking the opening of the shell with a thin perforated film of limestone origin, allowing gas exchange. food stops, but nutrition continues thanks to reserves stored in the form of glycogen in the digestive tract and the albumin gland.
