I took that shot in Anilao, Philippines. I dive the area almost every weekend and have yet to see it again. The only other photo I have is it underbelly. Yes, I was able to pick it up and put it upside down. It was soft to the touch. It walks on stubby legs. It clearly has a mouth with teeth.
Does anyone know what angles of photos should be taken to help any in case I come across it again?
