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.

This is only the second adult specimen ever collected of this species. Barr et al, 2015, described the species based on a single mature female, plus larvae.

Edit: 11/21/2019 Dr. Cheryl Barr has examined this beetle. Unfortunately, it is a female. The male of this species remains undescribed for now.

Длина рачка около 2-2,5 см.
Был выброшен на берег расходящимися от судна волнами, позже снова перебрался в воду. В этой точке вдоль берега плавало около 10 рачков.

Согласно консультациям специалистов по бентосу ИФБиБТ СФУ, в Енисее обитает только один байкальский вид рачков-бокоплавов с шипами - Pallasea cancelloides.
