It is known for its advanced compound eyes. Brittle stars have long, thin arms emanating from a small, disk-shaped body and are about the size of an outstretched human hand.〔(Brittle Star Found Covered With Optically Advanced "Eyes" )〕 They belong to the phylum of echinoderms, which includes sea urchins, sea cucumbers, and sea stars. ==Visual system== Its arms are covered with calcite crystals. In addition to functioning as an armor and giving structural support, the crystals make up its unique visual systems. They minimize spherical aberration and can detect the direction of incoming light. The lenses work by filtering and focusing light on an underlying photoreceptor system. Nerve bundles under each lens, presumed to be light-sensitive, transmit the optical information to the rest of the nervous system.〔 The only known animals to employ a similar visual system were the now-extinct trilobites. Phototropic chromatophores can change ''O. wendtii's'' color and regulate how much light will reach the photoreceptors. 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「Ophiocoma wendtii」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.
