How do jellyfish sting?

Jellyfish stings occur when their tentacles come into contact with human skin. The tentacles of a jellyfish contain tiny, stinging cells called nematocysts that release venom upon contact.

These nematocysts are tiny, capsule-like structures that contain a coiled, harpoon-like filament. When the tentacle comes in contact with skin, the filament is triggered and shoots out, delivering venom into the skin. This venom can cause a range of symptoms, from mild itching and skin irritation to severe pain, muscle cramps, and even cardiac arrest.

If you are stung by a jellyfish, it is important to remove any tentacles that may be stuck to your skin. You can use a pair of tweezers or the edge of a credit card to scrape them off. You should then rinse the affected area with saltwater (not freshwater) and apply heat or cold to help alleviate pain and swelling. In severe cases, medical attention may be necessary.

Jellyfish sting with their tentacles, which are covered in tiny stinging cells called nematocysts. Each nematocyst contains a harpoon-like structure that is triggered when it comes into contact with a predator or prey. The harpoon injects venom into the victim, which can cause pain, swelling, and other symptoms.

The severity of a jellyfish sting can vary depending on the type of jellyfish, the size of the tentacle, and the amount of venom injected. Some jellyfish, such as the box jellyfish, have a very potent venom that can be fatal to humans. Others, such as the sea nettle, have a less potent venom that typically causes only mild discomfort.

If you are stung by a jellyfish, it is important to remove the tentacles as quickly as possible. You can do this by using a credit card or other flat object to scrape them off your skin. Do not rub the tentacles, as this can release more venom.

Once the tentacles have been removed, you should wash the affected area with soap and water. You may also want to apply a cold compress to help relieve pain and swelling. If the sting is severe, you should seek medical attention.

Here are some tips to help prevent jellyfish stings:

• Avoid swimming in areas where jellyfish are known to be present.
• Wear a full-body wetsuit when swimming in areas where jellyfish are present.
• Check the water before entering it for any jellyfish.
• Be aware of the jellyfish season in your area.
• If you see a jellyfish, do not touch it.

By following these tips, you can help to prevent jellyfish stings and have a safe and enjoyable time in the water.
