Snails of the world:Papua New Guinea and surrounding islands In this region the colorful snails of the genus Papuina (Papustyla)can be found,which belong to the family of the Camaenidae. Some of them are very rare like P.fergusoni,while others seem to be more common like P.hindei,or even abundant like P.xanthochila. Its body is green and the shell a transparent white giving it good camouflage against the leaves. Unfortunatly the introduction of carnivorous snails to battle against the invasion of Achatina fulica did a lot of harm. Other attractive snails are the Megalacron,Forcartia and Rhynchotrochus genera. Also the genus Chloritis is present in this region.

It has four subgenera which are endemic. Very interesting slugs are those of the family Athoracophoridae.They have a very visible tracheal system in their lungs.Because this is unique in the Pulmonata class they have been given their own order:Tracheopulmonata.These slugs can also be found in Australia and New Zealand.
