As promised, here is a link to view a video clip of the micro-explorer camera in action. In this clip we were able to observe an adult male underneath a large rock. Note the rocking motion of the head, a behavior rarely witnessed in the wild or captivity. Thanks Greg, I defintiely need to get my hands on one of these cameras!
For those who are not familiar with what a hellbender looks like, here is a dorsal view of an adult that measures about 16 inches from head to tail. Note: Look for the flat, rounded head in the video if you are having trouble recognizing any of the shapes.
