The Japanese seahorse reaches a maximum length of 8.0 cm, is usually dark brown and has a relatively long tail, a ridgelike coronet and flattened spines. Many seahorse species look similar, so in addition to any distinguishing features, individual specimens are identified using a series of specific measurements and counts of anatomical features such as spines and tail rings. H. ''mohnikei'' has a planktonic stage in the first six months of life, after which they settle, preferably in ''Zostera'' sea grass beds or estuaries, and begin to breed. They are ovoviviparous and the males carry the eggs in a brood pouch. While several seahorse species are used in traditional Chinese medicine, H. ''mohnikei'' is not one of them. ==Distribution and feeding== The mid-range of Q and maybe P and U. ''mohnikei'' distribution is around 28 N latitude.〔Foster SJ, Vincent CJ. Life history and ecology of seahorses: implications for conservation and management. Journal of Fish Biology 65(1):1-61, 2004.〕 For many years the only confirmed distribution was around Japan. However, it was recently observed as far south as the Palk Bay coast of southeastern India.〔M. Thangaraj A. P. Lipton. Occurrence of the Japanese seahorse Hippocampus mohnikei Bleeker 1854 from the Palk Bay coast of south-eastern India. Journal of Fish Biology 70(1): 310-312, 2007〕 It has also recently been positively observed in Kampot, Cambodia.〔http://www.marineconservationcambodia.org/Marine-Conservation-Cambodia-News/Marine-Research-News-Cambodia/Hippocampus-Mohnikei-first-recorded-sighting-in-Cambodia.html?ref=nf〕 It is also suspected to be in the waters around China, Thailand and Viet Nam. They have a planktonic stage during the first six months of life, when they are between the lengths of 15.1-45.5 mm, in which they drift with other plankton in the water column.〔 As they grow their food preferences shift from smaller items such as Oithona ''davisae'' and Penilia ''avirostris'' to larger food species.〔Kouki Kanou and Hiroshi Kohno Early life history of a seahorse, Hippocampus mohnikei, in Tokyo Bay. Ichthyological Research 48(4):361-368, 2001〕 After the planktonic stage, they prefer to settle in ''Zostera'' sea grass beds and estuaries.〔(FishBase.org page on H. mohnikei )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Japanese seahorse」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
