I spent about 45 minutes observing a large (150 cm?) Andrias davidianus yesterday at an aquarium in Hakone, Shizuoka Prefecture. It swayed about 20 degrees about every 10-15 seconds, both to the left and to the right.
Does Erik or Ed or anybody else with experience with these animals know what it the purpose of this swaying and how common it is? My guess was that it was because these animals normally dwell in river areas with a current, and there was no perceptible current in this one's case.
I'll post a photograph or two of this magnificent creature later
