May 20 of this year marks Endangered Species Day, created to raise awareness, engage conservationists, and ultimately advocate for the protection of thousands of the world's species facing extinction.

The last decade has marked a dramatic increase in the risks facing species from rhinos to bees. In 2016, the animal trafficking market grew to an estimated $23 billion. Many researchers have called the additional loss of animal life to habitat change, pollution, climate change, and other factors a global epidemic.

To help raise awareness around animals at risk, Stacker looked to the World Wildlife Fund and The American Wildlife Foundation to identify species with a conservation status of "endangered" or "critically endangered" that face a high likelihood of extinction.
