Hi,
Yes, amazing, isn't it? Wood-eating catfish researchers would be a natural, glad you forwarded it (actually., I've found that many amphibian enthusiasts, myself included, are also interested in catfishes, lungfishes, eels, loaches and other such fish). The observation was reported by a researcher at the Agumbe Rainforest Research Station, founded by legendary herpetologist Rhom Whittaker. I had the pleasure of once hunting snakes with Mr. Whittaker, but was not involved in this research; merely passing along the info as it did not draw much attention on the net.
Best, Frank
