Video by @joelsartore | During moonlit nights, off the coasts of southern Japan, Brazil and Argentina, you might get lucky enough to see a flower hat jelly like this one emit fluorescent lights from its tentacles. These invertebrates have no brain, heart or real eyes and yet, incredibly, they are predatory animals. To hunt, these jellies will hide amongst the seagrass, waiting for an unsuspecting fish to swim by. By stinging their prey with their venomous tentacles, they’re able to subdue it and will consume entire fish at a time. While a sting from this jelly will definitely hurt and likely leave a rash, it is not fatal to humans. This flower hat jelly was photographed at @AquariumPacific, where they are displayed under moonlight conditions to highlight their fluorescence. For a portrait of this beautiful jelly, follow @joelsartore.
