1. West African Black Rhinoceros
Hunted for its horns, which are sold on the black market as aphrodisiacs in countries like China and Yemen, the last of these rhinos disappeared from Cameroon in west Africa in 2006.
This bird, native to Maui island in Hawaii, inhabited the southwestern slope of the Haleakala volcano on the island. It wasn’t discovered until the 1970s, and immediately its numbers began to decline.
By 1997 there were only 3 left in the wild, and they were officially declared extinct in 2004.
2. Zanzibar Leopard
The zanzibar leopard was a unique leopard species only found on the island of Zanzibar, an island off the coast of Tanzania in east Africa. As the island evolved during the 20th century, people began coming into contact with the leopards more and more.
Locals also believed that the leopards were kept by witches and actively sought to exterminate the cat. Conservation attempts in the 1990s were unsuccessful.
4. Pyrenean Ibex
This species of wild goat lived in the Iberian peninsula until being hunted to extinction in 2000. Skin samples from the last pyrenean ibex were used to clone one in 2009, but it died from lung complications shortly afterwards.
5. Golden Toad
This boldly colored toad was found high in the mountains of Costa Rica. Pollution, habitat loss, and a fungal virus all contribute to its extinction in 1989.
