Let’s begin !
So, What are Moon Jellies?
We can describe a moon jellyfish as an alien creature with a translucent body and having a moon-like bell that looks like an Alien UFO. Unlike an alien, it has long tentacles, but the moon jelly has small tentacles for capturing the prey and using it as self-defense when attacked.

Jellyfish are invertebrates, so they don’t have bones and have neither brain nor heart.
Surviving Without Brain
They have no brain but they do have a lot of nerves making a ring nervous system for controlling sensory and motor action.
These nerves help the jellyfish to perform automatic reflexes when stimuli like touch, temperature and salinity come. For example, their nervous system sends chemical signals to the tentacles to shrink their muscles for swimming smoothly.
No Heart, No Problem !
Without heart, they survive by responding to the stimuli like light, balance, chemical changes and touch coming from the surroundings. For this, they take the help of the ring nervous system, located just below the epidermis (outer layer of skin for protecting your body from harm).
Catching preys without eyes
As they don’t have eyes, they just keep floating and due to its bioluminescence, prey comes near and the ring nervous system senses it and sends signals to the tentacles for capturing the prey. This is the reason why jellyfish hunt their prey and survive without having any eyes.
No Teeth, but have Thin Hairs
They don’t have teeth but they do have thin hairs for pulling in prey into the stomach. Unlike humans who eat food by chewing, jellyfish swallow their prey whole. They digest their prey through the help of enzymes for breaking down the food into tiny parts and sucking the nutrients from them. After absorbing all the energy, they throw the waste through the mouth.
Do moon jellies feel pain?
As they don’t have a brain, so they don’t feel pain. Their whole body is made up of 95% of water and they have a ring nervous system, a set of nerves for sensing and responding to the stimuli in the surrounding.
Are moon jellies smart?
Yes, moon jellies are smart even if they do not have brains. They have a set of nerves called the ring nervous system, making them smart enough for capturing the prey and self defense when a predator arrives.
How fast can moon jellies swim?
According to a lab research, they swim at a speed of 0.007 meters per second which means they can swim 17 milliliters in 2.5 seconds.
What Colour are moon jellies?
They have a slightly bluish or pinkish color. Both of their bell and tentacles have translucent white color. Sometimes, the dome-shaped bell shows several shades of pink, blue or purple because of eating different prey.
Their bell has half-circles in the middle, which are reproductive tissues for helping females in internal fertilization of eggs (to get sperm from the mouth and fusing to the eggs).
Moon Jellyfish Sting
What happens when touching a normal Jellyfish ?
When touching a jellyfish, tiny hair triggers a defense mechanism and thus jellyfish will sting you. They also release venom onto your skin where you touched them and may get to the bloodstream. Very poisonous jellyfish make you dead within minutes and non-poisonous jellyfish give you no harm.
So, if you see a jellyfish washed on the beach, then don’t touch it because it may be poisonous and could make you dead through poison if it stings you.
So, Can I touch Moon Jellies?
Yes, you can touch them without any fear because they are non-poisonous, don’t hurt and are safe to humans for touching.
They are nearly painless when you touch them, you just feel a slight reaction even if it stings you because it can’t pierce through human skin. So, don’t freak out when it stings you !
Got Sting, Now What ?
If you have got sting, there’s no need to panic, its not serious and cannot penetrate human skin. What they live is just a minor sensation. If you are a sensitive person, then feeling a little bit irritation is common for you and may last for 10 days depending on your sensitivity. There’s no need to worry, irritation will go soon and you will be fine.
What to do if irritation is not recovering?
You can the fastest way to cure a jellyfish sting by using a First Aid Care. You just have to carefully remove visible tentacles with the help of fine tweezers. Then, put hot water on your skin that should be 110 to 113 Fahrenheit (43 to 45 Celcius).
If simply putting hot water doesn’t work and still you feel irritated then, put a paste of Baking Soda and Sea water onto the contact area.
Use an over-the-counter anti-itch cream like diphenhydramine (Benadryl®) to relieve irritation. Please consult a doctor if the irritation is extreme for a better medication. If someone gets stung in the mouth, in or around eye, on a significant area of skin, or in the genital area, seek medical attention.
Sting of Most deadliest jellyfish
Australian box jellyfish is the deadliest and most venomous jellyfish. When you see them, won’t look dangerous but if it stings then, you will be dead within minutes. Their scientific name is Chironex fleckeri and are often found in warm coastal waters of the Indo-Pacific and Northern Australia Oceans.
You can survive the jellyfish like moon jellies which have no poison, but you cannot survive the poisonous ones like box jellyfish.
Some of the box jellyfish are so poisonoius that they can make you dead within minutes. The remaining box jellyfish makes a person dead in 4 to 48 hours. The person becomes dead because of Irukandji syndrome, a painful and lethal condition caused by jellyfish sting. In this condition, a person has to suffer severe pain, hypertension and life-threatening cardiac problems.
Which jellyfish has the most painful sting?
The stings of the Irukandji jellies are so painful that they can induce fatal brain hemorrhages, are already sending 50-100 individuals to the hospital each year. You can get the idea of how powerful the sting is “its 100 times greater than a cobra and 1,000 times greater than that of a tarantula,” Said Robert Drewe.
Sting of Non-deadliest Jellyfish
The sting of non-deadliest (non-venomous) jellyfish lasts up to 2 hours, so you get relief from severe pain after that much time. However, the problem of itching may last up to 1 week. If the sting of the jellyfish has severely hurted your skin, then the lines of red or purple color could last for even weeks.
You should immediately go to the hospital for diagnosing the injury and get treatment quickly after being stung by a jellyfish.
Predators of Moon Jellies
Sea anemone commonly kills and eats Moon Jellies that come into their range. While other predators like Tunas, Sharks, Swordfish, Sea turtles, Penguins, Spadefish, Sunfish, Loggerhead turtles also kill them. When they are washed up on the beach, they are killed by foxes and other terrestrial mammals and birds. Some people in East Asia also like to kill and eat them.

Moon Jellyfish on Beach
What to do if you find a jellyfish on the beach?
Jellyfish often come on the beach because of strong storm or tides and also they are not so good swimmer.
If you see a jellyfish on the beach and don’t know what to do, then just keep everyone away from that jellyfish because they can hurt you, even if they are dead, they still have venom present in the tentacles for stinging you. If they are very poisonous, they can make you dead within minutes and if they are non-poisonous, you will feel nothing. So, the better choice is not touching jellyfish on the beach.
In an experiment, Moon Jellyfish lived up to 48 minutes, so they can survive for this much longer time even outside of ocean water. Most of the jellyfish dies quickly when washed up on the beach. Even if they are dead, they can sting you because their stinging tentacles are still active.
