• •Barking geckos, previously thought to be a single species, were found to be nine distinct species.
• •The discovery was made through analyzing mating calls, DNA, and physical traits.
• •The new classification allows for a more accurate assessment of the geckos' characteristics and distribution.
• •Integrative taxonomy, using multiple data types, was key to this discovery.

Scientists have identified nine distinct species of barking geckos in southern Africa, a significant increase from the previously known three. This discovery was made possible through the analysis of the geckos' unique mating calls and genetic sequencing, revealing that some species were separated by millions of years of evolution. The research emphasizes the importance of using integrative taxonomy, which combines multiple types of data to classify species accurately. The findings will help scientists better understand the geckos' distribution, habitat preferences, and physical traits, ensuring appropriate conservation efforts.
