The Darwin's frog, named after Charles Darwin, faces extinction after the introduction of the chytrid fungus to their habitat.

Southern Darwin's frog tadpoles grow up inside the vocal sacs of their fathers and are 'born' through their mouths as froglets. The brooding dads made an incredible 7,000-mile journey by boat, plane, and car to London Zoo from their remote island off the southern coast of Chile.

This is a landmark moment in our work to protect the Darwin’s frog from the devastating impact of chytrid fungus,’ said Ben Tapley.
