Beautiful recently extinct animals

 Pyrenean Ibex
The Pyrenean Ibex has one of the more interesting stories among extinct animals, since it was the first species to ever be brought back into existence via cloning, only to go extinct again just seven minutes after being born due to lung failure. The Pyrenean Ibex was native to the Pyrenees, a mountain range in Andorra, France and Spain. The Pyrenean ibex was still abundant in the fourteenth century (Day 1981). The Pyrenean ibex’s population declined due to a “slow but continuous persecution” and disappeared from the French Pyrenees and the eastern Cantabrian mountain range by the mid-nineteenth century. Its situation has been critical since the beginning of the 20th century, when it was estimated that the Pyrenean population in Spain numbered only about 100 individuals. Since the beginning of the 20th century, the population never rose above 40 individuals. In 1981, the population was reported to be 30. At the end of the 1980′s the population size was estimated at 6-14 individuals. The last naturally born Pyrenean Ibex, named Celia, died on January 6th, 2000, after being found dead under a fallen tree at the age of 13. That animal’s only companion had died just a year earlier due to old age.

 Bubal Hartebeest
Although it once roamed throughout Northern Africa and the Middle East, the deep-rooted mythology (once domesticated by the ancient Egyptians as a food source and for sacrificial purposes) which surrounded the animal was not enough to save it from European hunters who began hunting them for recreation and meat. People who resided in Morocco shot these animals for fun, and for hunting, which wiped large herds of them out. Many Hartebeests were captured and were kept alive (e.g. in the London Zoo from 1883 to 1907), but they eventually died out. The last Bubal Hartebeest was probably a female which died in the Paris Zoo in 1923.
 Javan Tiger
Javan Tigers were a subspecies of tigers which were limited to the Indonesian island of Java. In the early 19th century Javan tigers were so common, that in some areas they were considered nothing more than pests. As the human population increased, large parts of the island were cultivated, leading to a severe reduction of their natural habitat. Wherever man moved in, the Javan tigers were ruthlessly hunted down or poisoned. Natives carried much of the hunting out, a surprising thing since they considered the tiger a reincarnation of their dead relatives. The last specimen to have been seen was sighted in 1972, although there is evidence from track counts that the animal had lingered into the 1980’s. The last track counts to yield evidence of the tigers was held in 1979, when just three tigers were identified. The leading cause of their extinction was agricultural encroachment and habitat loss, which continues to be a serious concern in Java.
 Tecopa Pupfish
The Tecopa Pupfish was native in the Mojave Desert, in Inyo County, California, United States of America. This fish subspecies was originally found only in the outflows of North and South Tecopa Hot Springs. It was first described by Robert Rush Miller in 1948. Its decline began in the early 1940s when the northern and the southern spring which were about 10 yards apart were made into canals and bathhouses were build. The popularity of Tecopa Hot Springs in the 1950s and 1960s led to the building of hotels and trailer parks in that area. By 1981 the Tecopa Pupfish was officially delisted by the United States Fish and Wildlife Service and it became the first animal which was officially declared extinct according to the provisions of the Endangered Species Act of 1973.
 Baiji River Dolphin
The Baiji population declined drastically in recent decades as China industrialized and made heavy use of the river for fishing, transportation, and hydroelectricity. As China developed economically, pressure on the river dolphin grew significantly. Industrial and residential waste flowed into the Yangtze. The riverbed was dredged and reinforced with concrete in many locations. Ship traffic multiplied, boats grew in size, and fishermen employed wider and more lethal nets. Noise pollution caused the nearly blind animal to collide with propellers. In the 1970s and 1980s, an estimated half of Baiji deaths were attributed to entanglement in fishing gear. Only a few hundred were left by 1970. Then the number dropped down to 400 by the 1980s and then to 13 in 1997 when a full-fledged search was conducted. The dolphin was declared functionally extinct after an expedition late in 2006 failed to record a single individual after an extensive search of the animal’s entire range.
