Southern Chinca is especially rich in caves. These caves are inhabited by a unique, still little-known fauna, especially diverse are different groups of millipedes.

Currently, a joint team of researchers from Russia, China and Germany studies general adaptations of millipedes to the life inside caves using comparative morphology.
