Imagine being one of just 100 humans left on the planet. While it seems like something out of a disaster movie (the CW’s The 100 comes to mind), it’s actually a reality for a number of exceedingly rare animals. These critically endangered species are under constant threat. While animals with very small populations like the red-crested tree rat have miraculously appeared after centuries of presumed extinction, other species aren’t so lucky. The case of the White Rhino begs the question “how do you bring back a species with just one elderly male in existence?” and the Seychelles sheath-tailed bat is losing a difficult battle against nature.
These 12 animals are among the rarest in the world – less than 100 of them exist in the wild. Although conservation efforts are being made to save these species, will it be enough?
