Strange Luminescent Water Creature in the UK

There is a long history of unexplained luminescent water creatures sighted off of coasts or from water craft. I once heard from a former US Navy Captain that his aircraft carrier was once pursued by one that was twice the length of his ship! Recently one was caught on tape in Bristol Harbor. According to the December 5th  report in The UK Telegraph:

"Experts were baffled after video footage emerged of a glowing “alien-like creature” swimming in Bristol harbour.

Stunned eyewitnesses filmed a mystery luminescent, tentacled being, which was flashing a variety of colours, floating close to the top of the water

Videos of the strange marine object in the city’s historic docks were posted on Youtube and Twitter with many claiming to have seen an alien.

Marine biologists admit they are baffled, but claim the footage could be a marine salp which had drifted off course by the weather."
