Crystal Jelly
Scientific name: Aequorea victoria
Aequorea victoria, also sometimes called the Crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America. The species is best known as the source of aequorin (a photoprotein), and green fluorescent protein (GFP); two proteins involved in bioluminescence.
Firefly
Scientific name: Lampyridae
Fireflies create rhythmic flashes of light as a form of communication, each species having its own unique blinking pattern. Although all fireflies nominally glow as larvae, only some species produce light in their adult stage, and the location of the light organ varies among species and between sexes of the same species. Fireflies have attracted human attention since classical antiquity; their presence has been taken to signify a wide variety of conditions in different cultures.
Flashlight Fish
Scientific name: Anomalopidae
Anomalopidae (lanterneye fishes or flashlight fishes) are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named. These light organs contain luminous bacteria and can be "shut off" by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract prey, and evade predators.
