As adults reach the end of their lives, they go through spawning events where they produce eggs. Most jellyfish stings are painful, but few species produce a sting potent enough to kill a human. Other animals in the marine and fresh water environments and even some terrestrial animals that have been observed to prey of jellyfishes usually do so when their primary source of food becomes greatly dwindled, either by seasonality or effect of a permanent climate change. This invertebrate has special characteristics that make it unique, and has even aroused the interest of science.

Some species have also been recorded to suddenly flash a bright light to startle and shock their prey as soon as they have touched the jellyfish, thus making it easy to hold on and feed their prey. Researchers even say that jellyfish are able to release their excessive chemical energy in the form of light as a by-product.

Most bioluminescent ones live throughout the oceans depths, but most exist in one particular twilight zone of the ocean that ranges between 660 feet (201 meters) to about 3,300 feet (1,006 meters) deep. Instead, they have an elementary nervous system called a nerve net. The nerve nets allow them to detect light and smell, and respond to other stimuli. This releases energy, and light is emitted. The epidermis is the outer layer. Most jellyfish bioluminescence is used for defense against predators. Fun Facts: Aequorea victoria produces the green fluorescent protein (GFP). They also have protective covers over their eyes that protect that area of the body as well from the sting or toxins that a Jellyfish may be able to deliver.

Researchers study the health of the jellyfish populations. This species is rarely bioluminescent in nature but by placing it under a black (UV) light the GFP can be observed. Therefore in Aequorea victoria like species, luciferase reacts with oxygen in the presence of the enzyme Aequorin along with the cofactor Calcium to form oxyluciferin by an oxidation reaction. First, the jellyfish falls to the ocean floor, or coral reef. At times, the crystal jelly can give off a green glow around the edge of the bell. They have mouths that they use to feed on the zooplankton. It is impenetrable to most, so the jellyfish cant sting them the way they usually do.

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. The bell can pulsate to provide . The unsuspecting animal draws closer until the predator is close enough to snap its jaws shut, capturing its prey. Without them it would be very hard for fish, turtles, and birds to be able to find enough to eat. Kaylee is a science writer and outdoor enthusiast.
