Scientists have identified four previously unknown species of chameleon living in the isolated mountain forests of northern Mozambique. These "sky island" habitats, separated by vast stretches of savanna, have allowed unique species to evolve over thousands of years, hidden from the wider world until now. 

What makes the discovery even more remarkable is that these newly identified chameleons may already be at risk, as the forests they depend on are under pressure from habitat loss. However, being aware of their presence means that we can take steps to help ensure their survival and the conservation of their unique ecosystem.  

The discovery highlights how much we still have to learn about the natural world, especially in places that have received less scientific attention. It’s also a powerful reminder of the importance of protecting habitats – for the species we know and all those we’re yet to recognise.
