These Are the 17 Most Critically Endangered Species on Earth According to the WWF

And then there were three.

Yesterday, one of only 4 of the world’s remaining northern white rhinos was put down in a United States zoo (she was 41 years old). Unless an ambitious surrogacy program is successful in birthing northern white rhino cubs using the sperm of southern white rhinos, it’s reasonable to assume the species will be extinct soon.

Nearly a year ago, we gave you a list of animals that might not even make it though 2015. And while we’re happy we’ve so far been wrong, Northern white rhinos now appear to be the most in danger of become extinct all together. Currently, however, there are also 17 other species that fall under the WWF’s ‘critically endangered’ category….
