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.
生活在白海的海岸亚潮带与欧洲的北极圈海岸在哪里它反映一个宽的适应北极圈的生态学环境.(参考文献 1371) 发现在深度浅的地方, 沿着海岸有软的, 泥底部, 接近冰与在大陆架上.(参考文献 1371) 时常在偶而完全地非常淡水的淡水捕获, 进入河的嘴与潮间带而且向上游移动.(参考文献 1371) 主要吃甲壳动物与蠕虫, 但是吃小鱼.(参考文献 1371) 分类的问题被解决。
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。
