We are losing species across all parts of our ecosystem at a thousand times the natural rate.

Within this loss of biodiversity are species that are often extremely unusual in the way they look, live and behave, and that represent a significant amount of unique evolutionary history.

The Zoological Society of London has set up the EDGE of Existence programme, which highlights and conserves one-of-a-kind organisms that are on the verge of extinction.

From frogs that give birth through their skin to mammals that are immune to cyanide - they are species unfamiliar to most of us and in urgent need of conservation attention.

Ndoni Khanyile travels to the Seychelles to help EDGE researchers track down some of the world's most unique species and look at what is being done to help protect their habitats.
