Weird alien-like creature spotted in Bristol harbour (Video) - Dec 3, 2013

On December 3, 2013 videographer John Tombe captured a strange glowing “alien-like creature” floating in the waters of Bristol Harbour.

Alex Gordon-Lennox, 22, said: "It was just floating down the harbour. I've never seen anything like it before. I only noticed it because it was flashing and was so bright. I was out with some friends that night so we watched it travel down the water a bit and then it just seemed to disappear. It looked a bit like a jellyfish or a squid or something. It was amazing."

Andrew Spooner, a software engineer from Bristol: "The creature looked very organic, and it moved fluidly through the water as if it were a creature rather than say a machine that someone had made to look like Jellyfish.”

Dr Steve Simpson, from the School of Biological Sciences at Bristol University: “It's very intriguing - I don't really know what to make of it.”

There is a possibility that it is a special type of jellyfish or a marine salp. There are various marine animals that have biological illuminating abilities and they are able to make themselves flash.

It is possible that it is a marine creature which has been brought into the harbour because of the storms or maybe it was trying to shelter from the stormy seas.

Meanwhile, experts cannot agree on what it is that uploader John Tombe has captured on camera.
