The crystal jelly eats copepods, and other planktonic creatures, comb jellies, and other jellyfish. They are soft animals that can produce glowing light from their body which is actually due to the chemical reaction that is happening metabolically within their cells and tissues. The average life span of the species is approximately 10 to 15 years in the captivity. Of course it depends on where they live and their size. The medusa part of the life cycle is a pelagic organism, which is budded off a bottom-living polyp in late spring. Brusca, Richard C., and Brusca, Gary J. Invertebrates.

Aequorea species can be fairly difficult to tell apart, as the morphological features on which identifications are made are mostly the numbers of tentacles, numbers of radial canals, numbers of marginal statocysts, and size. The biggest type is the Emperor penguin, which can be a meter tall. This research also marked the beginning of research into green fluorescent protein which was summarized by Shimomura. In addition to its transparency, it has hundreds of tentacles of different sizes. When activated, the organs produce a beautiful blue-green glow. 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.

It reverts to its polyp stage when resources are low or when it feels threatened. They reproduce through a complex life cycle involving polyps, strobila, and medusae stages, and face threats from sea birds, sea turtles, and plastic pollution. They play a vital role in the oceans ecosystem, serving as primary prey for larger animals and offering insights into water quality through their population health.

Shimomura notes that this species in general shows great variation: from 1961 to 1988 he collected around 1 million individuals in the waters surrounding the Friday Harbor Laboratories of University of Washington, and in many cases there were pronounced variations in the form of the jellyfish. 3 What is the lifespan of a crystal jellyfish?

The unsuspecting animal draws closer until the predator is close enough to snap its jaws shut, capturing its prey. This species is thought to be synonymous with Aequorea aequorea of Osamu Shimomura, the discoverer of green fluorescent protein (GFP). Researchers even say that jellyfish are able to release their excessive chemical energy in the form of light as a by-product. It then uses the strength of the same structures to pull them into its mouth and swallow them whole. What kind of food does the Aequorea victoria eat?
