Interesting Facts About Jellyfish: Charismatic And Gelatinous Creatures!

Jellyfish and jelly-like sea animal come in a vastly various range of forms. They are gooey; they sting, and even they are perhaps not the first thing which comes to your mind when you think of seafood.
However, jellyfish are surprisingly interesting creatures. They can easily mesmerize aquarium crowds like some other organisms, and they are some of most ancient animals of the Earth which are still alive today.
Jellyfish or popularly known as jellies are the main non-polyp type of individuals of the phylum Cnidaria. They’re classified as free-swimming marine creatures comprising of a gelatinous umbrella-shaped bell and the trailing tentacles. The stinging tentacles can be used to capture prey while bell can pulsate for locomotion.
jellyfishJellyfish are found in each ocean, from the deep to the surface sea. Scyphozoans are exceptionally marine, but a few hydrozoans exist in freshwater. Huge, usually colorful, jellyfish are very common in coastal zones throughout the world. Jellyfish have always roamed the seas for more than 500 million years, and perhaps 700 million years or even more, making them the oldest multi-organ creature.
They’re pointless creatures which live in the sea. They aren’t good-looking or cuddly, and they’re available waiting for you to step foot in the sea. They‘ll most likely be the final things on our planet as scientists have discovered in Japan.
A group of jellyfish is occasionally referred to as a swarm or a bloom. ‘Bloom’ is often used for a big group of jellyfish which gathers in a limited area, but may also possess a time component, referring to seasonal rises, or numbers above what was expected.
Another common name for a group of jellyfish is smack, even though this term is not regularly used by the scientists who study jellyfish. Jellyfish are ‘bloomy’ due to the nature of their life cycles, being developed by their benthic polyps often in the spring when plankton and sunshine increase. Therefore, they look rather suddenly and usually in huge numbers, even when an ecosystem is in balance. Using ‘swarm’ often indicates some active capability to remain together that a few species like Aurelia, the moon-jelly, exhibit.
Medusa jellyfish may be categorized as scyphomedusae (‘real’ jellyfish), cubomedusae (box jellyfish), stauromedusae (stalked jellyfish), or the hydromedusae, according to which clade their species belongs.
To understand more about these fascinating creatures, take some moments to reveal fun facts about jellyfish. You might be amazed at what you do not know about these oddly, charismatic and gelatinous creatures.
For a start, do you know that Jellyfish lay thousands of eggs once they’re killed and they never stop growing! Anyway, here are ten facts which you most probably did not know. Enjoy!
1. They do not require a respiratory system.
The skin or tissue of a jellyfish is very thin which the invertebrate can obtain its oxygen from diffusion, and hence does not require a respiratory system.
2. Tentacles of one variety can grow more than 90 feet long.
The biggest jellyfish species, the lion’s mane jellyfish, can have tentacles which extend longer than the blue whale, the biggest mammal on Earth.
3. Jellyfish do not have brains
Instead, jellyfish have some nerve nets that detect any changes in the environment and coordinate the responses of the animal.
4. Jellyfish powder has been used to produce salted caramel
Turtles eat jellyfish, and bigger jellies may also eat smaller ones, but are jellyfish acceptable for human consumption? One group of high school students in Japan developed a salted caramel recipe which uses powered jellyfish. It is not vegan for sure, but it’s one way to handle an invasive jellyfish bloom.
5. Jellyfish existed even when no dinosaurs lived on Earth.
6. A single jellyfish can produce as much as 45,000 eggs every day!
7. There exists a kind of jellyfish which resembles a plant. It often lies on the seabed upside down to receive energy from the sun.
8. The amount of venom found in the Box Jellyfish can kill up to 60 people!
9. Jellyfish are astonishingly great at shutting down the nuclear reactors
In the last decade, jellyfish blooms have been accountable for shutting down many nuclear reactors that often depend on ocean water intakes. The jellyfish swarms can easily clog the intake pipes, compelling facilities to cease operating temporarily.
10. Even a dead jellyfish can sting. Jellyfish kill more humans than sharks every year.
