This little critter is another type of scallop called Ctenoides Ales - known as the disco scallop.
It's a striking orange colour and has an electric blue flickering inside. This flickering is not bio-luminescence it's actually highly reflective material inside the scallop that's simply flipping over and over giving the impression of electricity.
This disco scallop is not native in the UK and is found in the central Indo-Pacific region.
