''Leptasterias aequalis'', common names little six-rayed seastar or six-armed star, is a species of starfish. This is a small species, with a total width of only about . The coloration is extremely variable. This seastar is found in the eastern Pacific Ocean, from Washington to Southern California. It lives on rocky shores, in the mid intertidal zone. Many sea-stars broadcast spawn their embryos, where fertilization occurs in the water column, however Leptasterias species brood their embryos locally. The stars form mating aggregations and the female sits on her brood for a period of 6-8 weeks while the embryos develop underneath. Eventually the embryos fully metamorphose into juvenile sea-stars and walk away, and thus can only locally disperse. ==External links== * Lots of good information at: () * CalPhoto image 1: () * CalPhoto image 2: () 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「Leptasterias aequalis」の詳細全文を読む スポンサード リンク
