Life of Nomura's Jellyfish

Life of Sea | Nomura's Jellyfish (Nemopilema nomurai) | Nomura's jellyfish is an enormous jellyfish like Lion's Mane jellyfish. Nomura's Jellyfish also known as Echizen kurage in Japan, a large Japanese jellyfish whose width is slightly greater than a height of a grown man. Nomura's jellyfish are often found in the ocean near Korea and China. Scientists believe they originated in the Yellow Sea and in Chinese waters. They live in waters near Japan. The main areas where they are found East China Sea and Yellow Sea.

These huge sea creatures can grow 1.83 meters in diameter and weigh over 204 kilograms. This creature is one of the largest species of jellyfish. Some look like they have eyes but they do not. They have no brains. Their bodies are at least 94% water. They also have no airways. The jellyfish's mouth was their anus. Their color is gray-brown with pink tentacles. Their predators are swordfish, tuna, sunfish, leatherback turtles, and people. Nomura's jellyfish eat plankton which they catch with their tentacles. These jellyfish can eat large crustaceans.

Their population is on the increase in the fishing waters and is a serious problem for the fishermen, because a large number of Nomura's jellyfish of gets caught in their nets. The cause for greater concern is that they catch with their toxic poison stingers or crush them to death. And often break the nets because of their weight. It is a serious crisis that has begun to make a living influence. An interesting fact about the jellyfish is the way people eat them. Chinese eat them with sesame oil and onions. Vietnamese eat them with red chillies, mustard in Korea, and Thailand as a noodle. The Americans think they taste "snot".

There are even reports that they are destroying the local fishing with their love of fish eggs and larvae. In some areas the density is said to be one hundred times more than normal. There are many theories that are said to be the cause of this explosion. One is global warming, where the seas are heated and are better suited for their breeding. And scientists blame the overfishing of the natural enemies of the jellyfish and pollution along the coast. The high levels of nutrients in the water are also associated with this sudden jellyfish bloom.
