How Fast Can a Jellyfish Run: Fact and Information

Jellyfish are one of the animals that many people fear on holiday to the beach, as jellyfish are known to have nasty stings. However, actually How Fast Can a Jellyfish Run: Fact and Information. They have some unique characteristics in their history and life cycle.


What do you know about jellyfish?

Bionic jellyfish are good at monitoring climate change in the oceans, how do he swim and moving. Do jellyfish really swim? Yes because it is the fastest animal and do not die, it also has an STFC jellyfish crew.


What group of animals is the jellyfish?

Jellyfish are a common term for a group of invertebrate animals from the phylum Cnidaria that is umbrella-shaped and has tentacles. There are so many types of jellyfish.


Can a jellyfish kill you?

The sting of a particular box jellyfish can kill a person in a few minutes. Other box jellyfish stings can cause death within 4 to 48 hours after being stung due to “Irukandji syndrome”. This is a delayed reaction to the sting.


How fast can a jellyfish move?

Usually, jellyfish swim at a speed of about Approx 2 cm/second. Although they can move faster, it does not help them in ensnaring their prey, their typical reason for using the “swimming” movement is waving the tentacles.


What jellyfish are the fastest?

Box jellyfish are very advanced among others. They have developed the ability to move rather than just drift, flying at speeds of up to four knots through the water.


How Fast Can a Jellyfish Run?

Speed of jellyfish stings

A Ferrari accelerates from 0-60 mph in 3 seconds. That’s 3 g. Jellyfish stinging cells ignite at an acceleration of 5 million g. It only takes 700 seconds for the sting to reach its target.

To make sure the weight of the jellyfish you can find out in the “weight of average jellyfish“? this will explain more details.


Don’t Be Underestimated, Here Are the World’s Most Dangerous Jellyfish Types

You must have heard the news about jellyfish attacks in certain seasons. Yes, most jellyfish do have stinging tentacles to survive. Plus, because of its color that tends to be transparent and blend with water, the presence of jellyfish is often unnoticed.

Sea nettle

Sea nettle or Chrysaora fuscescens has long, thin tentacles, and is commonly found in the Chesapeake Bay area off the East Coast of the United States. According to researchers, the phenomenon of sea nettle breeding is common and dangerous.

It has 24 tentacles that can reach as far as 6 feet in length. The sting is also quite toxic which causes excruciating pain, but fortunately, this jellyfish rarely takes a fatality.

Some species of animals use sea nettle as transportation to the beach and will sometimes eat pieces of sea nettle as a snack during the trip.


Lion’s mane

This jellyfish species is known as the largest of the other types of jellyfish. Its habitat range spans the North Pacific and the Atlantic Ocean, to the Arctic Ocean. It has a diameter of 6 feet over 7 inches, with the largest length ever recorded being 120 feet. The length of the tentacles of this jellyfish can reach 100 feet and is used for predation.

These jellyfish often swim in large groups, and according to researchers, stings from a jellyfish can cause severe pain and even allergies due to its protein-based toxins.


Cannonball jellyfish

Cannonball jellyfish or the scientific name Stomolophus Meleagris has a characteristic shape that is round like a cannon. It is recorded as living in the mid-west Atlantic Ocean and the east-central and northwestern Pacific Oceans.

The main food of this type of jellyfish is zooplankton. Cannon jellyfish are poison-producing, and their stings can cause mild heart disease in humans.



Its small size of about 0.2 inches and transparent color sometimes make Irukandji jellyfish difficult to avoid. Irukandji belongs to the box jellyfish family known as one of the most poisonous animals on the planet.

Irukandji venom is 100 stronger than cobras, both tentacles and bells of this jellyfish can sting. A single sting from Irukandji can be treated, but repeated stings from these jellyfish are almost certainly deadly.

Symptoms of Irukandji jellyfish stings include severe muscle cramps, pain in the kidneys and back, burning sensation, headaches, and vomiting.


Box jellyfish

Living off the coasts of Darwin and North Queensland, the box jellyfish is one of Australia’s most powerful singers and is responsible for 70 deaths in the country by wrapping their victims around with 3 meters long tentacles. These transparent jellyfish attacks are most common during the summer months and recorded deaths occur between October and May.

Box jellyfish inject toxins through small receptors along the tentacles, so the severity of the sting is related to the number of tentacles touching the skin. In addition to being very painful, the poison attacks the muscles around the lungs and heart, which if left untreated can lead to death.


How Does a Jellyfish Sting Work?

A poisonous stinging device in jellyfish is referred to as nematodes. This organ is present in a special cell called cnida. Nemesis is used by jellyfish to catch prey and protect themselves from predators. There are also several species of jellyfish that use their nematodes to be able to stick to the bottom of the water.

Nematosis can still be active a few days after the jellyfish die. So, if you find a jellyfish stranded on the beach do not touch it even if it is dead.

From the results of the study Box jellyfish Species Chironex fleckeri including the most dangerous type of jellyfish due to the very high level of toxins and very high pain and fatality.

If you experience a jellyfish sting, there is some first aid that can be given. First, the victim must be quickly brought ashore. Next, do non-activation of nematosis by watering it using kitchen vinegar and leave for at least 30 seconds.

Because the results show kitchen vinegar is the most efficient to disable this nematosis.


Things to keep in mind, if exposed to jellyfish stings

Never flush the sting wounds of jellyfish using alcohol, urine, seawater, or freshwater, because it can aggravate the wound. The next step is to seek medical help immediately so that the victim can get further help as soon as possible.



Interesting Facts Jellyfish, Ancient Animals to Have Been to Space

Ancient animals

Ancient animal jellyfish have no bones, so the fossils are difficult for researchers to obtain. Nevertheless, scientists have evidence that this creature drifted in the world’s oceans for at least 500 million years.

It was likely that the lineage of the jellyfish was more than 700 years earlier, and that was roughly 3 times the age of the first dinosaurs. That is, jellyfish existed hundreds of millions of years before dinosaurs.


Can survive with changing seawater pH

Jellyfish continue to thrive in oceans whose ecosystems are disrupted by ocean heat waves, increased sea acid levels, overfishing, and various other human actions.

Uniquely for jellyfish, human activity has made them feel more at home. While corals, oysters, and any marine organisms that will be vulnerable to being affected even die from increasingly acidic ocean levels. Although, this does not mean that the jellyfish are immune.


Jellyfish are not fish

Clearly of the visible stature of the jellyfish, it is not a species of fish. Jellyfish belong to the agar-agar zooplankton or invertebrates of the cnidarian phylum. Taxonomically, jellyfish have a very diverse variety.


98% water, no brain, and liver

It has been said before that jellyfish are considered better at surviving the effects of changes occurring in the oceans. Well, maybe you’ve seen the movement or the way jellyfish swim in the water?

Jellyfish tend to easily blend in with their surroundings and follow gentle waves from ocean currents. That’s because his body consists of 98% water.

When you try to get the jellyfish out of the water and put them on land, then within a few hours the jellyfish disappear after their bodies evaporate into the air. They have a rudimentary nervous system.

Loose neural networks located in the epidermis are called neural networks, but there is no brain and liver. As well, the structure of their bodies is so thin that they can be oxygenated only by diffusion.


Some types of jellyfish have eyes

Some species of jellyfish have very complex visions. Like a type of box jellyfish that has 24 eyes, two of them can see color.

It is also believed that there are jellyfish with intricate visual sensors so that they can see with a full 360-degree view of the surrounding environment.


Some types may be timeless

At least one unique species of jellyfish namely Turritopsis nutricula may never actually die. When threatened, the species can undergo “cellular transience” which is a process in which the cells of the organism in its body become newly returned.


Defecate where they eat

What do you think? This is the uniqueness of jellyfish. They have only one hole whose function is as the mouth and anus.


The deadliest creature on Earth

All jellyfish have nematocyst or stinging structures, with sting strength varying depending on the breed. The world’s most venomous jellyfish are box jellyfish, capable of killing adult humans with just one sting in a few minutes.

In each box jellyfish, the poison can kill more than 60 humans. People who are stung will experience very painful pain. However, Australian researchers have developed a potential antidote to box jellyfish stings.


Researchers first began sending jellyfish into space

Aboard the Columbia space shuttle in the early 1990s, to test how they could adapt in a gravityless environment.

This is because humans and jellyfish rely on gravity-sensitive calcium crystals to orient themselves. The crystals are located inside the inner ear in humans and along the lower edges of the fungal-like body of jellyfish.

Therefore, the researchers wanted to study how jellyfish adapt in space to get clues about how they apply to humans.


Sizes vary

The smallest species of jellyfish are the genus Staurocladie and Eleutheria, whose tentacles are only 0.5 millimeters in diameter.

In contrast, the type of jellyfish with the longest tentacles in the world is Cyanea capillata. The tentacles extend 120 feet or 36.5 meters. The world’s largest jellyfish by weight is the titanic Nomura jellyfish Nemopilema nomurai, which can dwarf human divers. It can have a diameter of 6.5 feet and weighs up to 199.5 kg.
