Jellyfish might inherit the earth.
With changes to marine ecology through over exploitation and climate change jellyfish “blooms” seem to be becoming more frequent.
In 2011 they managed to close down the Torness nuclear power station in East Lothian – by blocking it’s sea water intake. http://goo.gl/zPrpN
They are also very beautiful – particularly when still in the water rather than stranded on the beach – and a little bit mysterious. This one – a Blue Jellyfish I believe – was on a Fife beach.
I came across this interesting website looking at jellyfish in the Irish Sea:
