The stream that runs through the cave runs through a narrow channel in the floor. In part, the channel is full of rotting wood. This bug emerged from the rotting wood and walked along the wall next to the stream. When I tried to maneuver it into a better position for a photograph, it initially tried to hide in a crevice. When that did not work, it ran down the cave wall into the stream and stayed under the water for about 2 minutes before emerging. Another larger version of the same isopod species ran past while I was trying to photograph this one.
