Well I learned that this is a defensive stance for the BS. Dotty takes that stance anytime she is confronted with a bigger fish. Backside turned and head up. (Picture borrowed from Lorraine's photo gallery)
Here it is again seen in my BS, but the tang got a little too close, so she snapped!
Here is another photo of Dotty defending her burrow against the blue ogre!
I also learned that Dotty will swim out of her burrow before pooing and if she has an accident in her burrow she will scoop it up in her mouth and spit it away from her burrow. I have seen this on numerous occasions. I observe her a lot!
