Animals and Plants
A number of unusual species of plants and animals are found in this desert, many of which are endemic and highly adapted to the specific climate of the area. One of the most well-known endemic plants of the Namib is the bizarre Welwitschia mirabilis; a shrub-like plant, it grows two long strap-shaped leaves continuously throughout its lifetime. These leaves may be several meters long, gnarled and twisted from the desert winds. The taproot of the plant develops into a flat, concave disc in age. Welwitschia is notable for its survival in the extremely arid conditions in the Namib, mostly deriving moisture from the coastal sea fogs. An area where Welwitschias are a common sight is found in the surroundings of the Moon Valley, including the eponymous Welwitschia Plains.
The Namib fauna mostly comprises arthropods and other small animals that can live on little water, but a few species of bigger animals are also found, including antelopes and gazelles (such as oryxes and springboks), ostrichs, and in some areas even desert elephants. All these species have developed techniques to survive in the Namib environment. A number of endemic darkling beetles species- such as the Namib Desert beetle- have bumpy elytrons with a pattern of hydrophilic bumps and hydrophobic troughs. These cause humidity from the morning fogs to condensate into droplets, which roll down the beetle's back to its mouth; they are collectively known as "fog beetles". Another beetle, the Lepidochora discoidalis, builds "water-capturing" webs. Black-backed jackals lick humidity from stones. Gemsboks (also known as Oryxes) can raise the temperature of their bodies to 40 °C in the hottest hours of the day. The desert is also home to meerkats and several species of lizards.
In 1934 it was observed that lions were common in the coastal regions, mountains, and ephemeral rivers, between the lower Kuiseb River and the Kunene River.

Famous quotes containing the words animals and/or plants:
“Shall we never have done with that cliché, so stupid that it could only be human, about the sympathy of animals for man when he is unhappy? Animals love happiness almost as much as we do. A fit of crying disturbs them, they’ll sometimes imitate sobbing, and for a moment they’ll reflect our sadness. But they flee unhappiness as they flee fever, and I believe that in the long run they are capable of boycotting it.”
—Colette [Sidonie Gabrielle Colette] (1873–1954)
“... feminism is a political term and it must be recognized as such: it is political in women’s terms. What are these terms? Essentially it means making connections: between personal power and economic power, between domestic oppression and labor exploitation, between plants and chemicals, feelings and theories; it means making connections between our inside worlds and the outside world.”
—Anica Vesel Mander, U.S. author and feminist, and Anne Kent Rush (b. 1945)
