The emerald green snail, green tree snail, or Manus green tree snail, scientific name Papustyla pulcherrima, sometimes listed as Papuina pulcherrima, is a species of large, air-breathing tree snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae. [3]
The shells of this species were in demand for making jewelry, and were popular with shell collectors and, partly as a result of this, the species is now near being threatened.
Distribution and habitat
[edit]P. pulcherrima is endemic to Manus Island in Papua New Guinea. This snail lives in trees, and inhabits rain forest areas up to 112 m (367 ft) above sea level.
Description
[edit]The shell of this species is a vivid green color, which is unusual in snails. The green color is however not within the solid, calcium carbonate part of the shell but instead it is a very thin protein layer known as the periostracum. Under the periostracum the shell is yellow.
Endangered
[edit]Overharvesting of the species for commercial purposes led to a decline in the population of this snail. Logging of the rain forest where this species lives is also a serious threat to its survival.[1]
The snail and its shell are protected under CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora)[4] and the species is listed in the IUCN Red List as near threatened as of 2015.[1]
Papustyla pulcherrima is the only foreign gastropod species that is listed as Federally Endangered in the United States since 2 June 1970.[5]
