Scallops are one of my favourite subjects to film and photograph underwater as they "dance" away when threatened by a predator. These were filmed in August and I wish I could have spent many more hours capturing them with different lenses. I've just notioced many more interesting subjects watching these clips again such as gobies, anemones and brittle stars. Looks like I will have to wait for next year now to capture these. This was filmed in the Skomer Marine Marine Conservation Zone where it is illegal to take scallops.
