Among the thoughts that ran through my head when I saw this video was the possibility that some form of alien life had found its way, or been planted into the deep ocean. There have been plenty of ocean going alien movies, and the numerous reports of UFOs entering and leaving the water, so why not leave something behind? Right? We know more about the surface of the moon than about the deepest parts of our own oceans.
Thing… was videoed by a remote camera operating along a UK oil drilling operation
No, it is not a hoax. It took a little looking but I did find out that this has a name. A very appropriate name indeed. This is video of a Deepstaria Enigmatica Jellyfish.
Not quite as large as it looks above, the Deepstaria is approximately 60 cm (around two feet for the metrically challenged). Normally found in Arctic and Antarctic waters, it has been seen in UK waters before and lives at depths from 829 to 1830 meters, it was discovered in 1967 by Sir Frederick Stratten Russell. But who could not easily imagine the first video images returned from the oceans of Europa showing something exactly like this.
