Why do jellyfish hurt you?

Jellyfish tentacles contain tiny stinging cells called nematocysts. Nematocysts are packed with venom, which is injected into the skin when they come into contact with something. The venom causes a variety of symptoms, including pain, redness, swelling, and itching. In some cases, jellyfish stings can even be fatal.

Not all jellyfish are dangerous. Some species have very mild stings, while others can cause serious injury. The box jellyfish, which is found in the waters of Australia and southeast Asia, is considered to be the most venomous jellyfish in the world. Box jellyfish stings can cause paralysis and death within minutes.

There are a few things you can do to reduce your risk of being stung by a jellyfish:

*Avoid swimming in areas where jellyfish are known to live.

*If you must swim in an area where jellyfish are present, wear a wetsuit or other protective clothing.

* Avoid touching or poking jellyfish, even if they are dead.

* If you are stung by a jellyfish, rinse the area with vinegar and seek medical attention.
