The lion's mane jellyfish ( Cyanea capillata ) is a kind of in the order of semaeostomeae (Semaeostomeae). It is also known under the name yellow nettle jellyfish and is usually colloquially referred to by coastal residents as "fire jellyfish". Other names are lion's mane jellyfish , arctic lion's mane and great lion's mane . This is due to the fact that the sight of the yellow nettles reminds some of them of a lion's mane.
features
The umbrella of the yellow hair jellyfish measures up to one meter in diameter and appears dark red to yellow. The jellyfish has 70 to 150 edge tentacles per group, which can be up to 30 meters long. It is similar to the blue nettle jellyfish , but is larger than it and has a different color.
distribution
Yellow hair jellyfish can be found in the Atlantic , in the English Channel , in the North and western Baltic Seas . In January 2019, a specimen was spotted in the Pacific off the Thai island of Ko Tao .
Way of life
Yellow hair jellyfish are pelagic animals, which means that they live free-swimming in open water. The animals live in smaller schools and feed almost exclusively on zooplankton . They catch the prey by spreading like an umbrella and slowly sinking to the ground. This is how small crustaceans get caught in their tentacles.
hazards
Touching the fine tentacles of the yellow haired jellyfish triggers the nettle cells , which penetrate the skin with the nettle tube and inject a poison into the victim. The skin reacts allergic, it is reddened, swollen and burning. The injury is treated medically like a burn.
Trivia
In the crime short story The Lion's Mane by the writer Arthur Conan Doyle , the British detective Sherlock Holmes has to solve a death, which is based on the victim's injury by a yellow hair jellyfish.
