Of this team, a few have vanishingly small populations within the double or unmarried digits. a couple of species, together with the Pinta Island gigantic tortoise and the Yangtze large softshell turtle, sit down squarely at the border of extinction within the wild with a inhabitants of one.
In 100 below 100, Scott Leslie tells the interesting tales of species in far-flung locations no one ever hears approximately, just like the northern hairy-nosed wombat, the Gorgan mountain salamander or the Irrawaddy river shark. towards domestic are the Vancouver Island marmot, the Wyoming toad and the Devil’s gap pupfish.

Although there are other bamboo-dependent lemurs in Madagascar, none is as endangered as this one.

Here, on top of the destruction of their habitat by agriculture and development, the desertification of grassland by the overgrazing of cattle, and the decline of their prey species, cheetahs are illegally hunted by poachers coming into the desert on newly created mining roads.
