Name/s: Coronate medusa, deep-sea jellyfish, Atolla jellyfish
Scientific name: Atolla wyvillei
Class: Scyphozoa
Description: This jelly ranges all the way from 3 cm (1 in) to 20 cm (8 in) in diameter, their bell resembles that of a UFO with tentacles that can grow up to 12 ft long. While in the depths of the ocean, they are completely transparent which helps them hide from their predators, though when attacked, they flash a blue light which attracts bigger predators who will eat the animal after the jelly, which has given it the fitting nickname of the alarm jellyfish1
Habitat: Around the globe, but found 1,000-4,000 m (3,280-6,561 ft)1
Threat: Not dangerous 2
Fun fact: The E-jelly, a tool developed by marine biologist Edith Widder based on the distress flashes of the Atolla jellyfish, has been effectively and successfully utilized to entice mysterious and rare deep-sea creatures for shooting and documenting. In an expedition funded by Discovery Channel and NHK to locate the creature, the gadget successfully attracted a big squid due to its imitation of the jelly3
