Forest elephants in the Ivindo National Park, Gabon. There is no road access to Ivindo national park, in Gabon, one of the last intact and unexplored rainforests in Africa. In 2001, during his megatransect of the continent, the biologist Michael Fay discovered the Langoue Bai, deep within Ivindo, a glade where elusive forest elephants, buffalos, gorillas and chimps romp with little fear of humans.
Gorillas knuckle-walk using both their legs and their long arms (putting pressure on their knuckles, with the fingers rolled into the hand). Gorillas rarely walk using only their legs. They can climb trees, but do not do so very often. Gorillas cannot swim.
