In the wild, the box jellyfish will live up to 3 months, but can survive up to seven or eight months in a science lab tank.
The Australian box jellyfish holds a powerful venom that is known to stun, injure, and even kill its prey. The jellyfish live no more than twelve months and float through the water.
Box jellyfish have venom in their tentacles that can sting and kill a person in under five minutes. Children are also at greater risk because of their smaller body mass.

11. Some jellyfish can lay as many as 45,000 eggs in a single night.
Box jellyfish are most commonly present in tropical Australian waters from November to April each year, with 8% of stings occurring outside this period. Stings most commonly occur in adult men in water less than 100 mm deep. About 37% of Australian box jellyfish stings occur in children.
Though there is no official 'oldest jellyfish ever', there is a very special species of jellyfish that scientists say may be immortal – biologically at least. Turritopsis dohrnii, dubbed 'the immortal jellyfish' may be the oldest living creature on the planet.
Irukandji jellyfish's stings are so severe they can cause fatal brain hemorrhages and on average send 50-100 people to the hospital annually. Robert Drewe describes the sting as "100 times as potent as that of a cobra and 1,000 times stronger than a tarantula's".
Certain box jellyfish stings can kill a person within minutes. Other box jellyfish stings can lead to death in 4 to 48 hours after a sting due to "Irukandji syndrome," a delayed reaction to the sting. It is important to carefully monitor box jellyfish sting victims for hours after a sting.
Jellyfish sting for the same reason many sharks bite, they bump into something they think might be food and try and eat it. Are jellyfish conscious? Jellyfish have no brains and therefore are not aware of their own existence. So no, while alive they are not “conscious”.
Green sea turtles in particular are the major predator of the box jelly. In fact, they may be the only natural predator of this type of jellyfish.
While box jellyfish are found in warm coastal waters around the world, the lethal varieties are found primarily in the Indo-Pacific region and northern Australia. This includes the Australian box jellyfish (Chironex fleckeri), considered the most venomous marine animal.
1. Box jellyfish – Chironex fleckeri
Known for lurking off the coast of Darwin and northern Queensland, the box jellyfish is one of the most potent stingers in Australia. It has been responsible for 70 deaths in the country and takes victims by wrapping its 3m tentacles around the unsuspecting prey.
Yes, jellyfish sleep. And the weird part is that jellyfish have no brain and they can still sleep. How is that? Writing this week in the journal, Current Biology, researchers describe how they discovered this unexpected behavior in an upside down jellyfish.
Where the jellyfish tentacles have touched the skin, there will be immediate severe pain and red whip-like lines. If there has been a large area of contact, the person's heart may stop, causing death. This can happen within a few minutes.
Numerous venomous species of jellyfish occur in Australian waters, including the box jellyfish and Irukandji Jellyfish. Box jellyfish are believed to have caused at least 69 deaths since record keeping began in 1883.
“Washing off the tentacles using vinegar is important as vinegar neutralises the unfired stinging cells.
These symptoms include severe back and headaches, shooting pains in the body, vomiting, and difficulty breathing. It is important to note that not all box jellyfish encounters are deadly. However, approximately 100 people die each year from stings by the deadliest jellyfish.
Even though the Box Jellyfish is a very aggressive type of species there are still some predators it has to contend with. Turtles are the biggest problem for them due to their shell protecting them from the toxins. They also have protection over the eyes.
The Irukandji jellyfish is a small, extremely venomous species of box jellyfish approximately two centimetres in diameter, making it difficult for swimmers to notice in the water.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Jellyfish predate dinosaurs by hundreds of millions of years. Jellyfish don't have bones, so fossils are hard to come by. Even so, scientists have uncovered evidence these creatures have been living in our Ocean for at least 500 million years!
The oldest single living thing on the planet is a gnarled tree clinging to rocky soil in the White Mountains of California. This Great Basin bristlecone pine (Pinus longaeva) has withstood harsh winds, freezing temperatures and sparse rainfall for more than 5,000 years.
