A strange and bizarre, alien fish or sea creature that glowed in a variety of colors showed up last week during the night on the surface of Bristol harbor in the U.K. (Europe)
Lot of people where there and pulled out mobile phones and videocamera and began taking photos and video as they speculated on the mysterious sighting that looked like some sort of jellyfish or giant squid. Seems so strange that was so glowing.
A suggestion could be a bioluminescent crystal jelly. They are known to produce flashes of blue light but aren’t often seen in these waters.
