one of the few shots i got of them in full that came out really well once offloaded from the camera and cleaned up. yes it was looking head down and floating like that. they float around mostly aimlessly in the current allowing their camouflage to make them appear as if they are bits of kelp floating along but do not be fooled they may not be setting speed records but they are capable of powered swimming and can catch some small swimming food animals. the large fin that can just be seen on the hump before the tail is one of the swim fins
