Aequorea victoria.

If we plunge the water in the ocean and we began to fall and fall until the light disappeared, and the pressure, dead silence and total darkness, we suddenly discover that there is a world of amazing animals, strange and fascinating. An example of these animals, may be the jellyfish Aequorea victoria or crystal jelly.

A bioluminescent jellyfish in the light of day is almost invisible, but in the darkness of the deep produces a beautiful light, a light which hypnotizes and traps prey in his wonderful tentacles filled nematocysts (cells that inject toxins).

Not long ago it was discovered (2009), yet little is known of it. If I am not mistaken is the only animal that produces green light, thanks to a green fluorescent protein (GFP, for its acronym in English, green fluorescent protein), produced only by the jellyfish Aequorea victoria.

It inhabits the west coast of North America, but as often happens lately with many jellyfish, the number of specimens of this species is growing due to the disappearance of predators.
