Liguus: Difference between revisions

'''''Liguus''''' is a genus of large [[Snail|land snails]], or, more properly, "tree" snails. They are especially notable for their large size, and for their often brightly colored [[animal shell|shells]], sometimes with complex patterns. Because of their visual appeal, the shells have been the target of heavy [[Collecting|collection]] pressure — a serious issue since some varieties are very scarce, and some are believed to have become extinct within the last century.<ref name="Power">Power, Emilio Jorge.
