生物學特性     字彙 (例如 附生動物)

They usually restrict themselves to sea ice and stay in relatively shallow areas of continuously moving ice, where open leads and polynyas regularly form. In some areas, they are known to haul out on shore, ascend streams, or live a pelagic existence away from ice and land for long periods of time. Feeds on many species of small invertebrates that live on, and in, the bottom; and fish (Ref. 1394).
