Jellyfish (also known as jellies or sea jellies) are free-swimming members of the phylum Cnidaria. Jellyfish have several different morphologies that represent several different cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000–1500 species that make jellyfish and many more that do not).[1][2] The jellyfish in these groups are also called, respectively, scyphomedusae, stauromedusae, cubomedusae, and hydromedusae; medusa is another word for jellyfish, and as such is used to refer specifically to the adult stage of the life cycle.

Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, are also found in fresh water; freshwater species are less than an inch (25 mm) in diameter, are colorless and do not sting. Many of the best-known jellyfish, such as Aurelia, are scyphomedusae. These are the large, often colorful, jellyfish that are common in coastal zones worldwide.

In its broadest sense, the term jellyfish also generally refers to members of the phylum Ctenophora. Although not closely related to cnidarian jellyfish, ctenophores are also free-swimming planktonic carnivores, are generally transparent or translucent, and exist in shallow to deep portions of all the world's oceans.

D.Gray-man is an ongoing Japanese manga series written and illustrated by Katsura Hoshino  






















D.Gray-man (ディー・グレイマン Dī Gureiman) is an ongoing Japanese manga series written and illustrated by Katsura Hoshino. The series tells the story of a boy named Allen Walker, a member of an organization of Exorcists who makes use of an ancient substance called Innocence to combat the Millennium Earl and his demonic army of akuma. Many characters and their designs were adapted from some of Katsura Hoshino's previous works and drafts, such as Zone, and Continue, and her assistants.

The manga began serialization in 2004 in the Weekly Shōnen Jump magazine, published by Shueisha under their Jump Comics imprint, and to date, 19 collected volumes have been released. It is currently slated to make the transition from weekly to monthly series in November 2009, when it begins serialization in Jump Square. There is also a spin-off novel series titled D.Gray-man Reverse, authored by Kaya Kizaki, that explores the history of various characters. As of August 4, 2009, Viz Media has released the first fourteen volumes in the United States. The manga has also been adapted into a 103 episode anime series that aired from October 3, 2006 to September 30, 2008 in Japan. The anime is licensed by Funimation Entertainment in North America.

The manga series has become one of the best-sellers for Shueisha. During its second release week, the 15th volume of the manga ranked as the second best selling comic in Japan. Although most reviewers compared it to other series from the same genre, they praised its moments of originality and its well-developed characters and their personalities.
