About this quiz
The Red List of the International Union for Conservation of Nature sorts assessed species into seven categories of rising risk. Vulnerable, Endangered and Critically Endangered species together are called threatened.
- Two more categories sit outside the scale: Data Deficient and Not Evaluated.
- Extinct in the Wild means a species survives only in captivity or cultivation.
- Each category has a two letter code, from LC to EX.
