Gorilla
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. They are classified in the genus Gorilla which is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after the species of "Pan"; the chimpanzees and bonobos.
Mammals of Glacier National Park (U.S.)
The elk, or wapiti ("Cervus canadensis"), is one of the largest species of deer in the world and one of the largest mammals in North America and eastern Asia. In the deer family (Cervidae), only the moose, "Alces alces" (called an "elk" in Europe), is larger, and "Cervus unicolor" (the sambar deer) can rival the "C. canadensis" elk in size. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark.
