If bottom-dwelling shark have parasites does the shark do bararolls .If that isnt parasites what is it.

does the shark always do barrel rolls every time it moves? if it does this it can be suffering from s stroke, wich can happen from being freaked out, or water temp change. sometimes when they have strokes they lose controll of their bouncey, sharks and fish have different air sacs that they can inflate or deflate by filling them up with air when they breath, this causes them to rise of sink. one of them can be damaged. or if it does it occasionaly it might be parasites and just trying to wipe them off against rocks or the bottom of the tank. good luck
