strange luminesent creatures

First time posting here lads just happened on this topic, I agree with thescotsman, work as an environmental scientist and most likely what you saw was Noctiluca scintillans, also known commonly as "seasparkle" because it is phosphorescent when disturbed.Large blooms occur all around the coast at any time of the year, a couple of years back there was a large bloom at Clonea Beach, it is also one of the marine algal types that causes "Red Tide", witnessed it at Clonea absolutely blood red sea bit like a Bowie video!

Tight lines to all.

Most definitely phosphorous and no harm attached to it. Used to get loads of it in the med in some of the cleanest waters you are likely to come across.

Yes the Noctiluca sp. theory is the best for me. Saw it as the waves broke in Inis Bofin in the eighties. A marvelous sight.
