I did wonder what it was initially... then it dawned on me it was a 2.5 ft lamprey! It looked like a great sea going leviathan that had been at sea for centuries gaining scars along the way... I do have a photo of it on the sandbank as it was helped up there with my boot. I helped it back as well and it tore off into the distance. If it had been a few months earlier I would have used it on my dead bait set up. Lamprey do bleed for ages and are a great pike bait!
Did you know that the Royal Air Force presented the Queen Elizabeth at her coronation breakfast with a lamprey pie? Mmmmmm.... it's meant to be a delicacy (I wouldn't)!
