簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 臀棘 0. Lateral line continuous to about the origin of the second dorsal fin. Head with no lateral line pores. Expanded parapophyses swollen and hollow, beginning on about vertebral centrum 5, containing outpouchings of the swim bladder. Brownish dorsally, becoming paler ventrally; with small dark blotches.
側線連續到大約第二個背鰭的起源。 頭部有沒有側線孔。 擴大了椎體橫突腫大與空的, 起點在大約椎骨的椎體 5, 包含泳鰾的外囊。 褐色的背面, 腹側變成灰白; 有小的黑色斑塊。
Lives in the coastal sublittoral zone of the White Sea and Arctic coasts of Europe where it reflects a broad adaptation to the ecological conditions of the Arctic (Ref. 1371). Found at shallow depths, along shores with soft, muddy bottoms, close to the ice and on the continental shelf (Ref. 1371). Often caught in greatly freshened and at times completely fresh water, entering mouths and tidal zones of rivers and traveling upstream (Ref. 1371). Feeds mainly on crustaceans and worms, but takes small fishes (Ref. 1371). Taxonomic problems to be solved.
生活在白海的海岸亞潮帶與歐洲的北極圈海岸在那裡它反映一個寬的適應北極圈的生態學環境.(參考文獻 1371) 發現在深度淺的地方, 沿著海岸有軟的, 泥底部, 接近冰與在大陸棚上.(參考文獻 1371) 時常在偶而完全地非常淡水的淡水捕獲, 進入河的嘴與潮間帶而且向上游移動.(參考文獻 1371) 主要吃甲殼動物與蠕蟲, 但是吃小魚.(參考文獻 1371) 分類的問題被解決。

Females produce about 6,000-90,000 eggs per year. From the shores, enters river mouths over sandy or rocky bottoms for spawning. Spawning sites are distributed in channels between islands or in depressions between the shore and shallow banks with strong tidal currents. 北極圈: 白色， Barents 與喀拉海海洋與從可樂果海灣到鄂比河小水灣。
