The Moon Jellyfish is a deep sea creature. They usually range from two to fifteen inches in diameter. Also, they are usually recognized by their delicate and exquisite colors, patterns, spots, or streaks. Since the bell of the Moon Jellyfish is translucent you can see right through it. Adult Moon Jellyfish are mostly identified for their horse shoe shaped organs which are visible through the bell. Moon Jellyfish have reproductive organs which are located near the bottom of the animal so, when the jellyfish eats its prey the area around the organs will become the color of its prey. It also has tentacles lining the center of the bell that drape down which make it easier when feeding. If Moon jellies are in an aquarium the adults only last for about a year. Unlike the polyp (baby Moon Jellyfish) which can live up to twenty-five years. Sometimes, the male will release a strand of sperm which the female will take in through her mouth to fertilize the eggs the female has inside of her. Later on the the eggs will develop in pockets in the arms that surround the mouth until the eggs are ready to be released. Once released they swim freely for a short period of time before they settle in one spot as polyp. They will then produce cloves and bud off of the polyp and are released in a water column. Then they begin to look like small plates with arms. Soon, after about three months, it will develop a complete bell. After that, the cycle will start all over again.
