The Arctic hare [2] (Lepus arcticus) is a species of hare highly adapted to living in the Arctic tundra and other icy biomes. The Arctic hare survives with shortened ears and limbs, a small nose, fat that makes up close to 20% of its body, and a thick coat of fur. It usually digs holes in the ground or under the snow to keep warm and to sleep.
Edible lichens are lichens that have a cultural history of use as a food. Although almost all lichen are edible (with some notable poisonous exceptions like the wolf lichen , powdered sunshine lichen , and the ground lichen [ 1 ] ), not all have a cultural history of usage as an edible lichen.
The Arctic consists of desert and tundra vegetations. The desert vegetation consists of algae, lichens, and mosses. Lichens are the most dominant plants. The ground is bare with a patchy cover of lichens and mosses. [24] Flowering plants are also seen but not as common. It only contains 60 species of flowering plants.
Nephroma arcticum, the arctic kidney lichen, is a species of foliose (leafy), terricolous (ground-dwelling) lichen in the family Parmeliaceae. It has a yellowish-green thallus up to 8 cm (3 in) across made of large lobes , with a dark, tomentose lower surface.
[6]: 3 Lichens do not have roots that absorb water and nutrients as plants do, [15]: 2 but like plants, they produce their own energy by photosynthesis. [16] Instead, lichen absorb nutrients from rainwater and the air [17]. When they grow on plants, they do not live as parasites, but instead use the plant's surface as a substrate.
Both rabbits and hares are almost exclusively herbivorous (although some Lepus species are known to eat carrion), [5] [6] feeding primarily on grasses and herbs, although they also eat leaves, fruit, and seeds of various kinds. Easily digestible food is processed in the gastrointestinal tract and expelled as regular feces.

The snowshoe hare is also distinguishable by the black tufts of fur on the edge of its ears. Its ears are shorter than those of most other hares. In summer, it feeds on plants such as grass, ferns, and leaves; in winter, it eats twigs, the bark from trees, and plants and, similar to the Arctic hare, has been known to occasionally eat dead ...
