Extinct animals.

West African Black Rhinoceros (2006)

The majestic West African black rhino was declared extinct in 2006, after conservationists failed to find any in their last remaining habitat in Cameroon. The West African black rhino was one of four subspecies of rhinoceros.

Cause of extinction: Poachers hunted the rhino for its horn, which is believed by some in Yemen and China to possess aphrodisiacal powers.

Zanzibar Leopard (1996)

One of several subspecies of leopard, the Zanzibar leopard made its home on the Zanzibar archipelago of Tanzania. It's still unclear whether this large cat is technically extinct — there are occasional unconfirmed sightings.

Cause of extinction: Locals believed the leopards were kept by witches, and aggressively hunted them. The animals were seen as evil predators that must be exterminated — and even the government was in on the campaign. In the mid-'90s there was a short-lived conservation effort but it was deemed too little, too late.

 

Golden Toad (1989)

The golden toad is not the only species to disappear in the past 40 years, but it might just be the brightest. This fluorescent amphibian was found in the high-altitude ridges of Costa Rica, but thanks to pollution, global warming and fungal skin infections, the species became extinct in 1989.
