![]() Turgi, the last of his kind, died in a plastic box at the London Zoo in 1996. A different type of carnivorous snail was later introduced in an effort to rein in the invasive species, but the plan hit a roadblock when the snails started eating the Polynesian tree snails instead of the intended targets. When settlers brought African giant land snails to the Pacific Islands in the early 20th century for use as lawn ornaments, the local Partula turgida population suffered. The main reason for the Polynesian tree snail's demise? Other snails, by way of humans. But the frogs died out within years, both in the wild and in captivity, and when Toughie died in 2016, the species likely died with him. More frogs like Toughie were eventually found (or heard croaking in the wild), and the newly discovered species Ecnomiohyla rabborum was officially recognized in 2008. He was given a new home in Atlanta Botanical Garden and named Toughie-a suggestion that came from the garden's amphibian conservation coordinator's 2-year-old son. #Earliest years of our species are lost to time skin#Researchers found him in Panama in 2005 during a rescue effort to save wild amphibians from a deadly skin fungus spreading through the jungle. Toughie wasn't just the last of the Rabbs' fringe-limbed tree frogs-he was the first of its kind ever discovered. Toughie the Rabbs' Fringe-Limbed Tree Frogīrian Gratwicke, Wikimedia Commons // CC BY 2.0 The cloned ibex died just minutes after it was born as a result of a lung defect, so sadly the effort to revive the Pyrenean ibex was short-lived. But that wasn't the end of her story: Using skin samples collected shortly after her death, scientists successfully cloned Celia in 2003, marking the first time a species was brought back from extinction. Her body was found in Spain in 2000, leading biologists to declare the Pyrenean ibex extinct following years of hunting pressures and competition from domestic cattle. Celia the Pyrenean IbexĬelia's status as an endling is up for debate. After she died she was immediately placed on ice and shipped to the Smithsonian in Washington, D.C., where her stuffed body can still be viewed today. Martha was born in the Cincinnati Zoo and lived there for 29 years before passing away in 1914, marking the end of her kind. Deforestation and game hunting helped fuel their dramatic decline. But by the turn of the 20th century, their population shrunk from roughly 6 billion to just a few captive specimens. Long before Martha, passenger pigeons were the most abundant birds in North America, flying in flocks of hundreds of millions and eclipsing the sun for hours at a time. He was last spotted in 1932, which means that unlike other animals on this list, his death wasn't documented. Despite efforts to rebuild the group, by 1929 only one heath hen remained: a male named Booming Ben. Unfortunately, all that progress was wiped out that May, when a wildfire burned through their habitat and led to the deaths of hundreds of birds. But conservationists weren't about to let the species die out so easily: A preserve was created for the struggling population and by 1916 their numbers had grown from 100 to 2000. After their habitat was changed by colonizers, heath hens, a subspecies of the greater prairie chicken, had all but disappeared from the northeastern U.S., and by 1870, the last birds that remained lived on Martha's Vineyard in Massachusetts. The extinction of the heath hen came at the end of a hard-fought preservation effort, making its story even more tragic. (Though some claim the species isn't extinct at all.) 2. He famously appears in videos taken at the zoo, the last images ever recorded of his species. Benjamin was captured in the wild and died only a few years later, likely due to neglect. Their numbers dwindled as a result of hunting, disease, and loss of habitat following Australia's colonization, and their line finally came to an end with Benjamin, a thylacine who lived at the Hobart Zoo in Tasmania from 1933 to 1936. The largest carnivorous marsupials of the modern age, they resembled dogs with the black stripes of a tiger and the pouch of a kangaroo. Thylacines, or Tasmanian tigers, were among the more unusual species to go extinct in the 20th century. ![]()
