Hey all, Was wondering if anyone has ever seen octopus with missing parts in the outerlayer of their mantle i.e holes where you can see white muscle underneath. I recently did a tour of the aquariums in the north of England and saw two aquariums where their octo's had this particular problem. One was a GPO another a common octopus. Neither seemed to be showing signs of autophagy and the loss of skin only seemed to be limited to the mantle. I thought orginally it could be due to sharp structures in the tank but then they didn't look like it and there were no structures. Also thought it might be due to poor diet, stress or possibly a bacterial infection. Anyone have any ideas?
