Visitors encounter monk hat jellyfish
The body is highly toxic and can be fatal in severe cases
On the evening of March 24, while enjoying the sea view on a beach in Shenzhen, some citizens found jellyfish washed up by the sea on the beach.
After comparison, experts found that this bubble jellyfish was actually a highly toxic monk's cap jellyfish.
Monk cap jellyfish is a kind of coelenterate, it belongs to the hydra class, blue-cyan, floating sac two pointed ends, flat bottom, shaped like a monk's hat, hence the name "monk cap jellyfish". Its buoyancy has a glowing membrane crown that adjusts its direction and floats on the surface like a sailboat in the wind.
The "murder weapon" used by the monk's hat jellyfish to sting people is those dense tentacles. The tentacles are densely packed with tiny stinging cells, which can secrete deadly toxins, and the toxins secreted by a single stinging cell are insignificant, but when the toxins secreted by thousands of stinging cells accumulate, their toxicity is no less than that of cobras, and the toxins of monk cap jellyfish belong to the category of neurotoxins.
It is known that if you are accidentally stung by a monk cap jellyfish, you will feel severe pain. The skin that has been "stabbed" by it will have banded red scars, as if it had been severely whipped.
This whip mark will last for 2 to 3 days before dissipating, and the toxin of the monk cap jellyfish will penetrate into the lymph nodes, causing allergic reactions, causing fever, difficulty breathing, shock, and even interfering with cardiopulmonary function, which can be fatal in severe cases.
Go to the beach to beware of animal "stings"
Seek medical attention promptly if adverse symptoms occur
According to experts, some jellyfish are very beautiful in appearance, but they are very fierce carnivores, and their slender tentacles are weapons. The spiny cells on the tentacles will shoot venom like poisonous silk, and the prey in the water will quickly paralyze and die after being stung by its sting.
According to statistics, there are about 30 kinds of jellyfish on the coast of the mainland that will sting people, and some jellyfish spines can secrete cobra-like venom, which quickly kills people after stinging, which is extremely harmful to humans.
In addition to jellyfish, everyone should also beware of other marine animal stings. Many times, in an emergency situation where a marine animal stings, there is no way to receive professional treatment immediately. Therefore, it is very important to master some first aid methods, which can save lives when it is critical!
1. Remove jellyfish tentacles (try to avoid direct skin contact with gloves, sticks, etc.);
2. Rinse the stinging area with seawater/vinegar;
3. Use a knife, razor, card, etc. to separate the stinging cells on the skin. It is best to apply with shaving bubbles or soap foam before scraping the cells.
4. Reapply the affected area with a vinegar/saline solution or rinse with seawater. Allow the stinging area to dry naturally, and take antihistamines with daily cleaning of open wounds and applying antibiotic ointment.
