''Salvelinus elgyticus'', also known as small-mouth char ((ロシア語:малоротая палия)), is a species of char found in the Elgygytgyn Lake in Eastern Siberia. == Habitat and description == This cold water fish is named after Elgygytgyn Lake located in Chukotka, Russian Federation, the only place where it is found.〔(Catalogue of Life: 21 December 2012 )〕 Together with the long-finned char it is endemic to this remote impact crater lake, being able to live in its environmentally very harsh conditions. The water in the depths of the lake where the small-mouth char lives is extremely cold, barely 2 degrees above freezing point. The lake is frozen about ten months every year, between September and July and some years it doesn't even fully thaw. This fish spends most of the year in total darkness.〔( Fly Fishing Russia - The Elgygytgyn Lake, Chukotka )〕 It is a small char species, dark colored with light spots, reaching a maximum length of just over 23 cm. Little is known about its habits and life cycle.〔(Salvelinus elgyticus - FishBase )〕 ''Salvelinus elgyticus'' is considered a threatened species by some authors,〔(Threatened fishes of the world: Salvelinus elgyticus Viktorovskii & Glubokovskii, 1981 (Salmonidae) )〕 but it has not been yet evaluated by IUCN. 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「Salvelinus elgyticus」の詳細全文を読む スポンサード リンク
