Fancy watching marine creatures squirting luminescent substance into the water? Try diving off the West coast of Ireland. That or watch the sea creatures do the flashing light dance (follow source link to watch it). It makes for one spectacular underwater lights show. 

Some of us who've been watching the Discovery Channel would know that animals in the deep have light-producing organs, thereby making them the only source of light at the bottom of the ocean. As such, it becomes almost an impossibility for land-dwellers like us to experience the awesome flashes of light these animals give off.

Thanks to the unmanned vehicle called Intensified Silicon Intensifier Target (ISIT), we can get a glimpse of the bottom-dwellers-exclusive lights show. The ISIT was designed to research bioluminescense in the deep sea.

While some might think that the light display is just all for show, researchers from the University of Bristol explained that the luminescence-squirting action is likely to be a defense mechanism. Perhaps to ward off unfriendly creatures.

To date, the researchers have seen: animals swimming while flashing lights; single flashes of light; and the light-squirting action. Perhaps one of the most fantastic displays would be that of light explosions the size of footballs. Show-offs!
