Animals on the EDGE

Purple frog

ZSL's EDGE of Existence programme highlights and protects some of the most unique species on the planet, which are on the verge of extinction.

These weird and wonderful species are Evolutionarily Distinct and Globally Endangered. Representing a unique and irreplaceable part of our world’s biodiversity, many EDGE species have been overlooked by conservationists – until now.

 

Explore our conservation work around the world, from Fellows to Projects to Expeditions, to learn more about these amazing species and support our efforts to maintain the diversity of life.
