On my recent climb to the Pinnacles limestone formation at the Mulu National Park, I encountered this strange grey and red snail displaying two long grey tentacles emerging from its back at an elevation of about 1000 metres above sea level. I have not seen this snail elsewhere and I see it turn up again and again in pictures from blogs of other folks who have climbed the Pinnacles – but till date, no one was able to give a positive ID.

Dear Kok Sen Wai,
We can’t believe we are posting two requests for very unusual Terrestrial Snails in the same day. The markings on the shell of your Snail are very similar to this example of Naninia obiana from Indonesia that is posted to FlickR. We did find a matching example on FlickR that is unidentified and Eric Hunt who posted the image made this observation: “The snail had two structures that it rapidly wiped over the shell like it was cleaning it.” There is also an image on Laura Loves It’s Blog and another example on FlickR. We will try contacting Susan Hewitt who frequently assists in the identification of Molluscs on our site to see if she has any ideas.
