I recently went down to the beach to take some very early morning photos. While I was waiting for the camera's time exposure to finish, I turned and went for a short walk. I noticed some things glowing behind me on the gravel bed, so I walked the 4 mtrs or so to where it was. At first I thought it was half a octopus but close by was several more pieces. It urns out that it was squid, I'm assuming that it was left by a fisher person after they had finished fishing. Going on where it was located and the run of the tides, it had not been in the water to allow any water borne creatures to enter the squid body parts. Unless they had moved through the damp gravel. Does anyone have thoughts as to why a dead squid would have the ability to glow?
