''Osedax'' is Latin for "bone-eating". The name alludes to how the worms bore into the bones of whale carcasses to reach enclosed lipids, on which they rely for sustenance. Scientists from the Monterey Bay Aquarium Research Institute using the submarine ROV ''Tiburon'' first discovered the genus in Monterey Bay, California, in February 2002. The worms were found living on the bones of a decaying gray whale in the Monterey Canyon, at a depth of . ==Anatomy and physiology== Lacking stomach and mouth, ''Osedax'' rely on symbiotic species of bacteria that aid in the digestion of whale proteins and lipids and release nutrients that the worms can absorb. ''Osedax'' have colorful feathery plumes that act as gills and unusual root-like structures that absorb nutrients. The ''Osedax'' secrete acid (rather than rely on teeth) to bore into bone to access the nutrients.〔(【引用サイトリンク】url=http://www.bbc.co.uk/nature/18594493 )〕 Between 50 and 100 microscopic dwarf males live inside a single female and never develop past the larval stage. 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「Osedax」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.
