11 Electrifying Facts about Jellyfish
Some are longer than a blue whale. Others are barely larger than a grain of sand. One species unleashes one of the most deadly venoms on Earth. Another holds a secret that's behind some of the greatest breakthroughs in biology. In every way, jellyfish are fascinating creatures and today we’re celebrating them with 11 wild facts!
Tumblr media
1. Jellyfish have inhabited the ocean for at least half a billion years, and they're still flourishing even as the sea changes around them.

2. Jellyfish are soft-bodied sea creatures that aren't really fish. They're part of a diverse team of gelatinous zooplankton, zooplankton being animals that drift in the ocean.

3. A noted feature of jellyfish is a translucent bell made of a soft delicate material called mesoglea. Sandwiched between two layers of skin, the mesoglea is more than 95% water held together by protein fibers. The jellyfish can contract and relax their bells to propel themselves. They don't have a brain or a spinal cord, but a neural net around the bell's inner margin forms a rudimentary nervous system that can sense the ocean's currents and the touch of other animals.

4. Jellyfish don't have typical digestive systems, either. These gelatinous carnivores consume plankton and other small sea creatures through a hole in the underside of their bells.

5. The nutrients that jellyfish consume are absorbed by an inner layer of cells with waste excreted back through their mouths.

6. One species of jellyfish glows green when it's agitated, mostly thanks to a biofluorescent compound called green fluorescent protein, or GFP. Scientists isolated the gene for GFP and figured out how to insert it into the DNA of other cells. There, it acts like a biochemical beacon, marking genetic modifications, or revealing the path of critical molecules. Scientists have used the glow of GFP to watch cancer cells proliferate, track the development of Alzheimer's, and illuminate countless other biological processes. Developing the tools and techniques from GFP has netted three scientists a Nobel Prize in 2008, and another three in 2014.

7. The jellyfish's sting, which helps it capture prey and defend itself, is its most infamous calling card. In the jelly's epidermis, cells called nematocysts lie coiled like poisonous harpoons. When they're triggered by contact, they shoot with an explosive force. It exerts over 550 times the pressure of Mike Tyson's strongest punch to inject venom into the victim.

8. The venom of one box jellyfish can kill a human in under five minutes, making it one of the most potent venoms of any animal in the world.

9. Jellyfish who may be the most successful organisms on Earth. There are more than 1,000 species of jellyfish, and many others that are often mistaken for them.
Tumblr media
10. Ancient fossils prove that jellyfish have inhabited the seas for at least 500 million years, and maybe go back over 700 million. That's longer than any other multi-organ animal. And as other marine animals are struggling to survive in warmer and more acidic oceans, the jellyfish are thriving, and perhaps getting even more numerous.
Tumblr media
11. Some jellyfish can lay as many as 45,000 eggs in a single night. And there's some jellyfish whose survival strategy almost sounds like science fiction. When the immortal jellyfish is sick, aging, or under stress, its struggling cells can change their identity. The tiny bell and tentacles deteriorate and turn into an immature polyp that spawns brand new clones of the parent.
From the TED-Ed Lesson Jellyfish predate dinosaurs. How have they survived so long? - David Gruber

me, spacey as hell: ive no way of knowing how close to death something minor ive donr just now like jump on my bed and hit my head on the wall put me me, spacey intensify: ive no way of knowing if im going to doe tomorrow or what would happen after i die me, spacey as possibly: im both relieved because it doesnt matter in any cosmic scheme if i died tomorrow because the sun will still engulf our planet on day and inevitably we will reach the universal heat death and my life will have never mattered, but im also terrified that if i died very different parts of me ive tried to keep seperate will colide and twp entirely seperate lives will meet and people will prob see me as a catfish and liar and thats a pretty scary thing even if im dead and it doesnt matter still spaced the hell out: will there be an after life and is my religion correct and will i be in some form of heaven or hell anf bases on my faith or my deeds? what is Consciousness in the scale of the cosmic universe as a developed mechanism of "life" in organisms and how different is it between animals, anf does our consciousness actually even matter or will death just snuff it out and the afterlife is a ludicrous construct? as beings composed of millions of things that are alive is our consciousness the construct of millions of smaller ones and our Mind is merely an illusion just like mold cells make up the illusion of a single stain? if in the effect that a human conscious is real and does transcend death in some mannor by the effect of a "god" then what creatures will reach that etheral plane? animals? insects? plants? microbes? virals? where will my loved ones be, will they join me in the same place, will they be smot to a different one based on sheer religious or spiritual belief, or by their own deeds? will we look on forever until the death of the universe and then by extension the afterlife might end, or, is it an eternal construct for consciousness? where was the human conscious before birth, where did it come from? is a consciousness fixed to a body? to a brain? can a consciousness be instructed to an artificial body the same way inr just comes to a baby? would a genetically created clone have a consciousness? what gices something is consciousness, its soul? me, giving up on all forms of thought: none of it matters at all to me right now because what matters is taxes and money and a job and my girlfriends and oxygen and food but 500 years from now these things never even mattered, could of never existed, effects no one, effects nothing. they might not even matter tomorrow, i could die in the next hour. i could die before i finish typing this and writing it will not of mattered. everything ive ever done or thought wouldnt matter. what happens after i die wouldnt matter. nithing would. gravity and time and distance and chemistry and consciousness and direction and existance and life and physics and society and necessity and importance and mathmatics and morality are all constructs to understand things and none of it matters because everything alive right now wont be in the next geo earth Eon, not a single human, not a single plant, not our planet, not our solar system. the mystery of how our universe came into existance wont matter when it comes to an end and when it does it wont matter how. what comes after death doesnt matter everything will eventually be there wherever it is. "everybody dies" is a concept you recognize as a child but infinantly ponder until it no linger matters.
