Fish species are lake trout, Arctic grayling, round whitefish (Prosopium cylindraceum), burbot, and slimy sculpin (Cottus cognatus), which feed on benthic chironomid larvae and snails, the latter controlling epilithic algae in the lake.

Effects of climate change on hydro-ecology of contributing basins in the Arctic 2009

The abrasive forces of the ice at the bottoms of glaciers may destroy all epilithic (rock-attached) lichen vegetation, but lichens once established are able to survive long periods of snow cover, and even glacial periods [121].

General characteristics of arctic species and their adaptations in the context of changes in climate and ultraviolet-B radiation levels 2009

Plants grow in a wide variety of inhospitable substrates including stone, rock (epilithic), recently decomposed stony soils, or sandy soils.
