Deep Sea Jelly display it's Bioluminscence

Deep in the ocean, where sunlight can no longer penetrate, lies an incredible world of darkness. And against all odds, this just happens to be the location of one of nature's most impressive artificial light shows. The creatures here have evolved their own ways of dealing with the darkness. Through a process known as bioluminescence, they have developed the ability to use chemicals within their bodies to produce light. LINK, Via: Seasky.org
