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.
Three main camouflage methods predominate in the oceans: transparency, [5] reflection, and counterillumination. [6] [1] Transparency and reflectivity are most important in the top 100 metres of the ocean; counterillumination is the main method from 100 metres down to 1000 metres; while camouflage becomes less important in the dark waters below 1000 metres.

[1] [2] They are distinguished from other jellyfish by the presence of a deep groove running around the umbrella, giving them the crown shape from which they take their name. Many of the species in the order inhabit deep sea environments. [3] Crown jellyfish are able to make light through bioluminescence. When they are touched, their bells will ...
The smallest jellyfish are the peculiar creeping jellyfish in the genera Staurocladia and Eleutheria, which have bell disks from 0.5 millimetres (1 ⁄ 32 in) to a few millimeters in diameter, with short tentacles that extend out beyond this, which these jellyfish use to move across the surface of seaweed or the bottoms of rocky pools; [51 ...
According to ABC News, bioluminescence is caused by dinoflagellates, a single-celled organism nicknamed "sea sparkles," and they emit light when stimulated by a disturbances in the water.
Bioluminescence is used by a variety of animals to mimic other species. Many species of deep sea fish such as the anglerfish and dragonfish make use of aggressive mimicry to attract prey. They have an appendage on their heads called an esca that contains bioluminescent bacteria able to produce a long-lasting glow which the fish can control. The ...
Scientists and bioluminescence enthusiasts have enjoyed a long streak of electrifying waves across Southern California. A specific type of algae bloom creates a bioluminescent effect, but catching ...
Creatures like jellyfish, starfish and sand dollars rely on the wind and current to move around. If an offshore storm or strong winds push these invertebrates too close to shore, they can get ...
