These functions are implemented through six research sections namely: –

Conducts research focusing on amphibians and reptiles of Kenya. Maintains the largest wet collection (over 30,000 specimens) for comparative research in Central and East Africa. Main areas of research include behavior, community ecology, physiology, anatomy, taxonomy and toxicology
