Project Noah stands for Networked organisms and habitats. It is meant as a tool that you can use to explore and document wildlife and harness the power of citizens scientists. See http://www.projectnoah.org/faq for more details on what how to can participate.
Looking up ‘snail’ under Organisms I found this picture taken at Ecuador, Loja of a transparent shell, seemingly a shell-less snail. Very peculiar! Being so transparent, it’s hard to identify it other than “Helix-like” which is as good as a shot in the dark.
Another one is this ‘Blue Rainforest Snail’ (my own words) from Costa Rica, Lim??n Prov.: Drymaeus sulphureus (Pfeiffer, 1857). It’s my favorite on the Project Noah site.
There are a lot of unidentified species on the site and probably most of them have been spotted near rural areas. Still it is a way to raise awareness for the flora and fauna around you and may serve an educational purpose.
