Scapa Flow, Kronprinz Wilhelm 080926

The dive starts with a brief glimpse of the 15 cm guns. Some divers went to visit the guns before me and their finning technique has room from improvement.....For the dive I then head to the stern for a look at the rudders. At 5:57 there is an interesting fish. I think it is a gurnard, but possible a sea scorpion. Any fish ID experts that can assist please? The video was shot using a GoPro 9 We were diving off Valhalla, skippered by Hazel Weaver.
