The Manus Island Green Tree Snail (Papustyla pulcherrima) occurs only on the island of Manus, off the northern coast of Papua New Guinea. If you were to look up in the trees you would see this magnificently camouflaged snail sitting under the green leaves. Its shell is so beautiful that it has been massively over-collected and it is now the only land snail from Papua New Guinea to be listed on the international CITES schedule which completely prevents its trade or export.
