Tell some amazing facts about Jellyfish ?

Glowing jellyfish goo could power medical devices
Another jellyfish-derived product takes advantage of the jellies' fluorescent protein, and could be used to power medical devices in the future.

Jellyfish are surprisingly good at shutting down nuclear reactors
In the past decade, jellyfish blooms have been responsible for shutting down several nuclear reactors, which often rely on ocean water intakes. The jellyfish swarms can clog the intake pipes, forcing facilities to stop operating temporarily.

Jellyfish will eat peanut butter
Peanut butter jellyfish! Need I say more?
Ok, I will: two Aquarists in Dallas, Texas created a saltwater/peanut butter mix and fed it to moon jellies. Apparently, the jellies found this mix to be an acceptable source of protein.

We would love to claim we conducted this trial with noble purpose, but the truth is that we just wanted to make peanut butter and jellyfish simply to see if it could be done," the

Some jellyfish look like trash bags.
They're known as Deepstaria enigmatica, and are usually found in the Arctic seas.

Jellyfish might take over the ocean
You may have heard that jellyfish are taking over the world's oceans. However, there's actually a good deal of debate about this issue among scientists.

Jellyfish first appeared about 650 million years ago and are found in every ocean, from the surface to the deep sea. Some are also found in fresh water

Medusa (plural medusae) is another word for jellyfish. Medusa is also the word for jellyfish in: Greek, Finnish, Portuguese, Romanian, Hebrew, Serbian, Croatian, Spanish, French, Italian, Hungarian, Polish, Czech, Slovak, Russian and Bulgarian

Since jellyfish are not actually fish, some people consider the term jellyfish a misnomer, and American public aquariums have popularized use of the terms jellies or sea jellies instead

A group of jellyfish is called a bloom or swarm

Jellyfish do not have a respiratory system since their skin is thin enough that the body is oxygenated by diffusion

Jellyfish do not have a brain or central nervous system, but rather have a loose network of nerves, located in the epidermis, which is called a “nerve net

Jellyfish are composed of more than 90% water. Most of their umbrella mass is a gelatinous material (the jelly) called mesoglea, which is surrounded by two layers of cells which forms the umbrella (top surface). The subumbrella (bottom surface) of the body is known as the bell

Jellyfish are dioecious; that is, they are either male or female. In most cases, to reproduce, both males and females release sperm and eggs into the surrounding water, where the (unprotected) eggs are fertilized and mature into new organisms

Box jellyfish venom is the most deadly in the animal kingdon and has caused at least 5,568 recorded deaths since 1954.

Each tentacle has about 500,000 sindasites which are harpoon shaped needles that inject venom into the victim

The lion’s mane jellyfish is the largest known species of jellyfish. The Arctic Lion’s mane jellyfish is one of the longest known animals and the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet). It was found washed up on the shore of Massachusetts Bay in 1870

Jellyfish are found in every ocean of the world. They are even found in some freshwater lakes and ponds.

Jellyfish range from the size of a thimble or the eraser tip of pencil to approximately eight feet in diameter with tentacles that reach 200 feet. That is as long as two blue whales

Each jellyfish tentacle is armed with thousands of cells called cnidoblasts. Inside the cnidoblasts are nematocysts, each of which contains a coiled stinging thread. When a fish or other object becomes tangled in the tentacles, the pressure inside the nematocysts causes the venomous threads to uncoil like a spring-loaded harpoon

The jellyfish’s main defense mechanisms are its stings and its transparent body, which makes it easy for it to hide

In an episode of Friends, one of the characters applies urine to a jellyfish sting. However, neuroscientists say urine is ineffective

Many neurosurgeons say that popular remedies for stings—such as vinegar, urine, or meat tenderizers—do not help stings. Instead, the best thing to do is get out of the water immediately, and wash the affected with salt water (NOT fresh water). Salt water will deactivate the stinging cells, while fresh or tap water will reactivate them. The best way to remove the cells is with something such as a credit card

Jellyfish have a short tube that hangs down from its body. The tube acts as both its mouth and its digestive tube. In some jellyfish, the central tube is surrounded by frilly pieces that look like curly ribbons in the water. These are called oral arms or mouth arms

Jellyfish do not have brains, hearts, ears, heads, feet, legs, or bones. Their skin is so thin that they can breathe through i
