China News network Sanya, January 24 (Zhang Yuehe) Recently some media reported that highly poisonous man-of-war jellyfish were found in a number of sea areas in Sanya. Sanya officials released news on the 24th, after an on-site investigation by experts, found that the species is not a highly venomous mitral jellyfish, but a close relative of the mitral jellyfish, the blue bottle mitral jellyfish. According to Wang Haishan, deputy director of the department of Fisheries at the School of Fisheries and Life Sciences at Hainan Tropical Oceanography University, there are no such jellyfish in Sanya waters, but their distribution is greatly affected by ocean currents and wind. Affected by the recent monsoon drift in the South China Sea, the blue bottle man-of-war jellyfish found near Sanya may have drifted here from lower latitudes.

Wang Haishan introduced that the blue capuchin jellyfish (scientific name: Physaliautriculus), English name Bluebottle, belongs to a kind of capuchin jellyfish, distributed in the warm waters of the Pacific and Indian oceans. There is no capuchin jellyfish in the coastal areas of China, but there are close relatives of the blue capuchin jellyfish. Blue bottle man-of-war jellyfish live on the surface of the ocean, like to gather together, drifting with the wind and currents. Compared to the jellyfish, which have dozens of tentacles on their mouth arms up to 10 meters in length, they are smaller, have only one long, main fishing tentacle, are less toxic, and can be a bit painful and swollen. No human deaths have been reported from blue bottle jellyfish stings.

The Physaliaphysalis, also known as the Portuguese battleship (Portuguesemano' war) is a deadly and highly venomous siphonophores found in the tropical Atlantic Ocean. Man-of-war jellyfish have poisonous stinging cells on their tentacles, which can cause severe pain and leave red whip marks that take two to three days to dissipate. The poison can seep into the lymph nodes and cause deeper pain. The sting can also cause allergic reactions and a range of effects, such as fever, shock and interference with heart and lung function. In severe cases, it can be fatal, but fatal cases are rare.

Wang said that if the foot or leg is stung by the blue bottle jellyfish, please remain calm. Walking may cause the venom to spread and increase the area of pain. Once you reach a place where you can clean and treat the wound, try to remain still. Use a plastic bag or towel to separate the jellyfish from the body, and carefully rinse the wound with seawater to make sure there are no tentacles left. Studies have shown that soaking a wound in hot water for 20 minutes can effectively relieve the pain caused by blue bottle jellyfish. The skin can withstand water temperatures of about 42 бу C, and can effectively treat stings. High temperatures can inactivate the proteins in the venom that cause pain.

Various departments in Sanya have jointly launched a publicity campaign to strengthen the prevention of blue bottle jellyfish, educate citizens and tourists about the relevant knowledge, and make warning signs and set up near the waters where the jellyfish are present. Citizens and tourists should avoid any aquatic creatures that cannot be identified while playing at the seaside. Do not touch, play with or panic. In case of emergency, please call 120 emergency number immediately. (Finished)
