Although slug species can vary enormously in appearance, and several are difficult to identify, further work, including DNA analysis, confirmed that they were distinct species. John R. Platt is the editor of The Revelator. Depending on their habitat and species, snails can survive about one to three years or even up to 25 years. They occur from Central Portugal to Central Scandinavia, in Britain up to Southern Scotland. The second whorl behind the shell mouth is wider than the whorl immediately behind the shell mouth. Tags: Conservation | Endangered Species | Extinct | Invertebrates | Wild and Weird. Slugs and snails are molluscs, a group that also includes Octopus, Squid and Cuttlefish, and one of the most successful invertebrate groups to have evolved. High rainfall and suitable habitat enable slugs and snails to thrive in the UK, much to the annoyance of many gardeners. Public Library of Science. 2008; Puillandre et al. In Ireland the species already is extinct, in Scotland it probably may be. × Terrestrial Map - 10km. Sources: Cameron R., 2003;. Cornu aspersum, like other snail species, is a hermaphroditic species (each individual having both male and female reproductive systems). Around 100 snail species and 25 slug species have been recorded in Leicestershire and Rutland (VC55). Gait Barrows supports strong populations of the species in mossy clint tops of Annex I habitat 8240 Limestone pavements at transitions to woodland, an unusual habitat for the species. The National Biodiversity Data Centre mapping system (Biodiversity Maps) integrates the mapping of terrestrial as well as marine data and is intended to serve as a portal for the geographic presentation of observational data on Ireland's biological data. The snail was discovered on a research trip in Borneo by a group of scientists and citizen scientists with Taxon Expeditions. The classic habitat in Ireland, favoured by the species, is the lagg zone, the outer part of raised bogs. Molluscs are not generally well recorded so all records are gratefully received. Different types of feed that is favored by the most investigated species, Achatina achatina, and the diet that is recommended to the farmers who is rearing this species, described here.

Of these, two are now considered to be extinct, five critically endangered, 14 endangered, 26 vulnerable and six “near-threatened”.

From the prehistoric age, human has been consuming snail meat because of its high rate of protein, iron, low fat, and including almost all the amino acid which is needed for human body.
