Mexico's unmapped underwater caves - in pictures
Photographer Klaus Thymann has been exploring the underwater cave system of the Yucatán peninsula, diving 1km underwater to where salt and freshwater meet. By mapping areas that have been untouched by modern civilisation, he hopes to raise awareness of the natural and human heritage of this unique ecosystem that will hopefully result in greater protection. He talks to Eric Hilaire about making his journey into a film, Flows, featuring music by Radiohead’s Thom Yorke
