In June 2008 I spent 14 days caving in the Battambang province of Cambodia. All the caves were dry. It was interesting to see some cave fauna, most of which is very similar to that in Malaysia. We found a few bat caves, most of which we didn't enter, because the stench of guano was overpowering. One cave in particular smelt of pure ammonia. The whip spiders seemed larger than those found in Malaysia.

An expedition report has been published in BCRA Speleology, 2009, No 13. Extensive information on the caves of Cambodia can be found in the book Atlas of the Great Caves and the Karst of Southeast Asia.

these snails are probably accidental visitors as the cave has several open entrances. They are possibly ariophantids, probably related to Macrochlamys (info from Dr M.Schilthuizen)

These Amblypygids, or whip spiders, seem larger than their Malaysian cousins

This snake is an accidental visitor to the cave. It was identified by Klaus Schulz as Oligodon taeniatus (Striped Kukri Snake).
