This jellyfish was caught in the eastern central Atlantic in depths between 100 and 600 meters. There was just individual of it. Can anybody identify it?
Thank you all very much for answering my question. Also my impression was Pelagia noctiluca but I wanted to cross check it. Unfortunately, there is no report about bioluminescence in this specimen (because already dead when reached the surface).
I agree with the other comments as it does look like Pelagia noctiluca and it does not have a sedentary life history stage. So finding it well offshore is very likely. Its nematocysts can penetrate human skin and can leave a weal. This is a further test! hope this helps. Dan
