''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.

Its genome size turned out to be moderate for a cnidarian, 213 Mbp. This is a tiny genome compared to human’s 3 Gbp.Jellyfish were probably the first muscle-powered swimmers in the open ocean. They appeared in the late Precambrian Era, a period of major geologic and ecological changes that preceded the Cambrian explosion of animal life. At some point in their evolution, jellyfish gained the ability to transition from a stationary polyp to a swimming medusa.October 2011 7:24 min.

Wikimedia Commons In years past, Jellyfish Lake was home to an estimated 5 million golden jellyfish. Without the sun, these organisms would die, robbing their hosts of important, life-giving energy. While the daily jellyfish migration is incredible in its own right, the migration pattern also plays an important role in the lake's ecosystem.Ocean. Increased sightings of jellyfish signal the rise in sea temperatures due to climate change. Jellyfish belong to the plankton, which are the marine group at the base of the ocean food web and are eaten by fish, seabirds and whales.
