Emerald GreenThe Emerald Green Snail (Papustyla pulcherrima) lives in rainforest trees, where its outrageous colour is perfectly matched to the lush forest foliage.The calcium carbonate shell of the snail is actually yellow, not green. The unusual colour comes from a layer of proteins that encapsulates the whole shell (the periostracum).This snail has been over-harvested for the jewellery trade, and is on the CITES (Convention on International Trade in Endangered Species) protected species list. If you see one for sale, don’t buy it!- OBImage Credit: https://goo.gl/8xa5r6 (with permission)Further Reading:- about CITES: http://goo.gl/VMv3X- the CITES lists: http://goo.gl/rDZdE -- source link
