Threats: This species is subject to very high rates of habitat loss and is heavily hunted Click on the slide images (below) to read more about their threats and conservation efforts. Find out about endangered species and ecosystems and learn about some of the most critically endangered animals and plants in the world - listed in the IUCN Red List of Threatened Species. Many species have been perceived as endangered because of hunting, habitat loss and degradation, chemical and noise pollution, human-induced climate change, unmonitored by-catches, poaching, accidents and disturbance and the pressure on the environment because of the rapid world population growth. The peaceful coexistence between species, which results from evolution by natural selection, has to be understood as an important fact in the workings of the great ecosystems around us." Paul Colinvaux, Why Big Fierce AnimalsAre Rare Natural selection is harsh only to the deviant aggressor who seeks to poach on the niche of another. ![]() A perfectly fashioned individual of a Darwinian species is programmed for a specialised life to be spent for the most part safe from competition with neighbours of other kinds. Survival of the fittest… What does it really mean? "Peaceful coexistence, not struggle, is the rule in our Darwinian world. The only other perissodactyls on earth today are horses, zebras, and donkeys (all belonging to genus Equus), and the strange, pig-like mammals known as tapirs. Rhinoceroses are characterized by their large sizes, quadrupedal postures, and single or double horns on the ends of their snouts-the name rhinoceros is Greek for "nose horn." These horns probably evolved as a sexually selected characteristic-that is, males with bigger, more prominent horns were more successful with females during mating season.It's Whale of a Study Time! Find out about "Things you can do" to protect our oceans, bees, rainforests and much more. Rhinoceroses are perissodactyls, or odd-toed ungulates, a family of mammals characterized by their herbivorous diets, relatively simple stomachs, and an odd number of toes on their feet (one or three). ![]() ![]() Habitat: Subharan Africa, Southeast Asia, Indian subcontinentĬonservation Status: Three species are Critically Endangered (Javan, Sumatran, black), one is Vulnerable (Indian), one is Near Threatened (white) Description Size: 4–15 feet tall, 7–15 feet long, depending on species sondaicos, Dicerorhinus sumatrensisĬommon Name: White, Black, Indian, Javan, Sumatran Scientific Name: Five species are Ceratotherium simum, Diceros bicornis, Rhinoceros unicornis, R. ![]()
