Endangered frogs born at London zoo after rescue mission in Chile

Group of Darwin's frogs threatened by chytrid fungus thrive in specially built room that mimics their natural habitat

Dozens of endangered froglets have been born at London zoo after conservationists launched an emergency mission to rescue members of the species from a remote national park in Chile.

Researchers rushed to Tantauco Park on the southern tip of Chiloe Island after tests confirmed that the lethal chytrid fungus had reached the nature reserve and threatened to wipe out some of the last remaining populations of Darwin's frogs.
