Transcript of crystal jelly

The Crystal Jelly has around 150 tentacles varying in size. It has a very large mouth and strong tentacles. The Crystal Jelly has no color because of its bioluminescence. It is completely transparent. It has no venom, but it has nematocysts on it’s tentacles instead of neurotoxins.

Crystal Jelly
The Aequorea Victoria has a habitat that mostly consists of salt water. They take home in the Puget Sound, the Straight of Georgia, Southeast Alaska, and most places along the U.S's western coastline.
The entire population of the Crystal jelly dies by mid autumn. Sadly, they can only live for about 4-6 months. The colonies of Crystal Jellyfish lay their eggs at around mid spring, for the species to hatch. Once the living Jellies die in autumn, their eggs hatch short after. The species likes to float aimlesly in the salty waters of the Pacific Ocean.

Taxonomy Classification
This protien has existed for more than 160,000,000 years in one species of jellyfish, the Crystal Jelly. That means that an animal with no brain has outlived the dinosaurs by a longshot. The protien is found in the photo organs of the jelly. It is the key to what makes the Crystal Jelly glow.
Green Fluorescent Protein
GFP can be extracted from the jelly for scientific purposes or for a material. It can be used as a protein in fluorescent markers, or it can be used in military-grade glowsticks.

Bioluminescent Facts
It is not understood how or why the jelly uses it bioluminescent qualites or what function it serves. The easiest way to see the bioluminescence is to stimulate the jelly's photo organs which contain GFP.
The bioluminescence of the Crystal Jelly comes from GFP (Green Fluorescent Protein). The Jelly does not glow continuously, instead it glows for a couple minutes at a time because its body cannot produce the protien quick enough for it to glow continuously. The jellies do not flash their luminous qualities to communicate, for they have no brain, limiting their social skills.

The Crystal Jelly has a simple diet consisting of whatever small organisms it can catch in its tenticles. Like we've said, jelly have no brains but they can taste! The nerves that are in the membrain process tastes and direct the animal to the taste. To the right you see a picture of zoo plankton which is mainly the jelly's diet

Fun Facts
Sea Jelly are a type of plankton, so yes, they are cannibals because their main prey is zoo plankton.
Sea Jellies can grow up to 3 centimeters in one day in the beginning
We know virtualy nothing about its ecology accept for the fact that the first couple of years it lives substrates such as shells.

What is bioluminescence?
Bioluminescence is the biochemical emission of light by living organisms, such as the Crystal Jelly.
