A rare fossa named Zaza has arrived at Chester Zoo from San Diego as part of a global breeding programme to help save the endangered species, which has fewer than 2,500 left in the wild. Conservationists hope he will successfully mate with Shala, the zoo’s resident female, to contribute to the species’ survival. Native to Madagascar, fossas face threats from deforestation, and this breeding effort supports both population growth and field research through vocal analysis. Zaza’s former keepers described him as curious and energetic, and conservationists are hopeful he will play a key role in preserving the species.
