These snails are threatened with extinction due to habitat loss and poaching. A snail is, in loose terms, a shelled gastropod. These animals can vary in size from under an inch in length (shell length) to more than 2 feet. Genome information will provide the much-needed basis for understanding molecular processes important for this species’ colour polymorphism, mating physiology and ecology. Whelks have a spiraled shell which varies in size and shape. A snail will not get cut if it moves over a sharp razor blade because of its protective slimy mucus. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails.
