Jellyfish are invertebrates along with corals, gorgonians and anemones, belong to a community called the Cnidarians. This species group has stinging cells that they are using for both to capture their predators and as a means of protection. This species may be invincible. It can play its life cycle in reverse, turning the adult medusa back into an immature polyp.
They have transparent bells fringed with light tentacles, and when they move along, this one almost appears as though the water itself is alive. Nevertheless, certain jelly-like animals, such as comb jelly, belong to the phylum Ctenophora. This taxonomic complexity has prompted marine scientists to wonder whether there is something like a jellyfish.
Let’s put aside these issues for now and plunge deep into the incredible realm of animals widely recognized as jellyfish.
1. They exist at a date earlier than dinosaurs hundreds of millions of years ago.
Jellyfish don’t have bones, but it’s impossible to find fossils. However, scientists have evidence that all these organisms have been bubbling along in the earth’s oceans for at least 500 million years. The jellyfish legacy is likely to go back much farther, probably 700 million years. That’s about three times the age of the very first dinosaurs.
2. They are 98% water, with no brain or heart.
Jellyfish appear to meld in with their surroundings, lightly undulating with ocean waves, although with legitimate reason: their bodies are made up of as much as 98% of water, says How Stuff Works. Within a few hours, as they land on the shore, they will vanish when their bodies evaporated into the sea.
15 Mind Blowing Facts About Human Nature3. There are three different names for a cluster of jellyfish.
Cluster of animals usually get their own names: a cohort of cows is a ‘herd’, for example, while a lot of fish swimming together is a ‘school’. Jellyfish classes may have three different names. A set of jellyfish is named “bloom,” “smack,” or “swarm.”
4. Jellyfish might attack a fully-grown human being.
Jellyfish are extraordinary creatures. They are neither jelly nor fish. Some of the most vibrant creatures in the world, but it’s safer to see do not handle these invertebrates. Their tentacles are lined with poison-filled darts. Only a few kinds of box jellyfish have such a venom which is deadly to humans, but a man who gets injured by one of these jellies could go to respiratory arrest or die within minutes.
5. GFP found in them is used for medicinal properties.
GFP, a green fluorescent specific protein found in crystal jellies, has significant medicinal properties. Mayo Clinic scientists have recently implanted a variant of GFP, and a rhesus macaque gene believed to suppress a virus that triggers feline AIDS in unfertilized cat embryos. Once the kittens were born, they glittered green under ultraviolet light, signaling that the gene had been effectively passed. Biologist Osamu Shimomura won the 2008 Nobel Prize in Chemistry for GFP discovery.
10 Totally Amazing Facts About Turtles6. Jellyfish replicate on their own.
When the jellyfish is split into two parts, the jellyfish rebuilds and produce two new species. Similarly, if the jellyfish is severely damaged, it can replicate itself and eventually produce hundreds of descendants.
7. Jellyfish has vision.
Despite the simplicity of their body design, some jellyfish have the ability to see. In reality, their vision may be remarkably complex for a few animals. For e.g., the box jellyfish has 24 “heads,” two of which are perfectly capable of seeing color. It is also believed that this animal’s detailed understanding of visual sensors makes it one of the few creatures on the planet to have had a full complete overview (360-degree view) of its surroundings.
8. Jellyfish tells us about deep sea propulsion.
Bell-shaped jellyfish movements have described the research methodology with a greater awareness of propulsion. The agility of their umbrella-like bodies allows them to pulse up and down without consuming much energy. Researchers have developed biomimetic robots with flexible bells that can lead one day to better underwater vehicles.
9. Jellyfish is especially effective at turning down nuclear reactors.
Over the last decade, jellyfish blooms have also been liable for shutting down several nuclear reactors that often depend on ocean water intake levels. Jellyfish swarms can block the intake pipes, causing the facility to shut down operations temporarily.
Unbelievable Facts About Ostrich - World’s Largest Bird10. Jellyfish have been through space.
In analyzing the effects of gravity, NASA sent a few thousand jellyfish into orbit with astronaut’s space shuttle Columbia in 1991, according to The Atlantic. The jellies worked just fine when in orbit, but the planet-born animals could not work naturally when they returned to Earth. The research posed fears that humans raised in space would still not be able to work in a standard-gravity environment. Such as jellies, human beings have calcium sulfate granules in our bodies, which react to gravitational force to tell us which way they ‘re going.
Bonus: There is a company that transforms jellyfish into eco-friendly nappies and feminine sanitary goods. If you can’t join them, defeat them and transform them into something quite valuable and usable.
