Nomura's Jellyfish

Nomura's Jellyfish is a very large Japanese jellyfish. It is in the same size class as the lion's mane jellyfish, the largest cnidarian in the world. The width of these jellyfish are slightly larger than the height of most full grown men. Growing up to 2 meters (6 feet 7 inches) in diameter and weighing up to 220 kilograms (ca. 450 pounds), Nomura's Jellyfish reside primarily in the waters between China and Japan, primarily centralized in the Yellow Sea and East China Sea. The jellyfish population has become such a substantial problem for Japan that it has led the government to form a committee to combat the problem. They have been creating kill-nets to catch and destroy the jellyfish before they can do any more harm, yet this typically only results in the aforementioned survival tactic of releasing their sperm and eggs. The problem with combating the jellyfish is that when they are under attack or killed, they release billions of sperm or eggs which connect in the water and attach to rocks or coral formations. when the conditions are favorable, the creatures detach from their home millions at a time and grow into more jellyfish. In an attempt to utilize the jellyfish in a productive manner, coastal communities in Japan are doing their best to promote jellyfish as a novelty food, sold dried and salted; students in Obama, Fukui (Japan) have managed to turn them into tofu, and jellyfish collagen is also reported to be beneficial to the skin.
