This region is known as the “midnight zone,” because no sunlight penetrates these depths. I'm pretty sure the tentacles sting, it would be a note-worthy thing if they didn't and I'm sure they'd mention it.And yes, those biologists and researcher get up to some crazy antics! It is because of these blue flashes that Atolla wyvillei has been nicknamed the “alarm jelly”. There has been evidence of them found in The deep ocean in a depth from 1,000 to 4,000 meters, an area commonly called the “Midnight Zone” (Unknown, 2013). The six known species inhabit the mesopelagic zone. All six Atolla species rely on bioluminescence -- light they produce themselves -- but the Atolla wyvillei uses the light in a defensive strategy that none of the other species employs.
