Thai Mountain Crab

Stelomon pruinosum

Description:

about 6" total width, I was told by a guide at the park that this was Stelomon kanchanaburiense, but it doesn't look like the photos I see online, so I'm going with S. pruinosum, as achmmad's suggestion.

Habitat:

tropical freshwater

Notes:

I spotted this crab and many other right near the campsite at Sai Yok National Park. I went to the park hoping to see an endemic species of crab but turns out it is only found deep in the park. I had to settle with these! I did a nightwalk in the streams surrounding my tent and found many crabs. The small purple ones are juveniles of the same species.

Lovely spotting Dan! I'm rather sure that this one is Stelomon pruinosum. Check it here http://decapoda.nhm.org/pdfs/28136/28136... there also some grayish pics of S. kanchanaburiense. Hope it help you!
