Bioluminescence

Learn About Bioluminescence

Bioluminescence, or the ability of an organism to create light, is one of nature’s most amazing phenomena, seemingly drawn more from science fiction than science and natural history. It has been estimated that 90% of the animals living in the pelagic zone (water column) are bioluminescent. However, information on bioluminescence in the deep-sea benthos (organisms that live on the ocean bottom) is sparse.

The Medusa lander is a stealth camera system that allows scientists to collect images of animals in the dark depths of the ocean. The optical lure of the Medusa is called the e-jelly, or electronic jellyfish, because it emulates the burglar alarm display of the deep-sea jellyfish, Atolla.
