''Leptasterias'' is a genus of starfish in the family Asteriidae. Members of this genus are characterised by having six arms although five-armed specimens sometimes occur. ''Asteracanthion muelleri'' is the type species. The taxonomy of the genus is confusing and ''Leptasterias hexactis'' seems to be a species complex. Some species brood their eggs. ==Species== The World Register of Marine Species lists the following species: 〔 *Subgenus ''Leptasterias (Hexasterias)'' Fisher, 1930 * *''Leptasterias alaskensis'' (Verrill, 1909) * *''Leptasterias camtschatica'' (Brandt, 1835) * *''Leptasterias coei'' Verrill, 1914 * *''Leptasterias leptodoma'' Fisher, 1930 * *''Leptasterias polaris'' (Müller & Troschel, 1842) * *''Leptasterias polymorpha'' Djakonov, 1938 * *''Leptasterias schmidti'' Djakonov, 1938 *Subgenus ''Leptasterias (Leptasterias)'' Verrill, 1866 * *''Leptasterias muelleri'' (M.
