Anguis fragilis
Other specially protected species that live in the caves are the slowworm ("Anguis fragilis"), grass snake ("Natrix natrix"), sand lizard ("Lacerta agilis"), dormouse ("Glis glis"), sparrowhawk ("Accipiter nisus"), and the collared flycatcher ("Ficedula albicollis"). For several groups of invertebrates that have been studied, among the most interesting are millipedes (Diplopoda), especially species "Brachychaeteuma bradae" and "Geoglomeris subterranea" who were first discovered in the Czech Republic at this location. "Androniscus dentiger" woodlouse are found in the cave system.
