11 New Species Found in Cambodia, Including Blue Pit Viper

When conservation researchers set out to count animals in Cambodia's Battambang Province three years ago, they hoped to spot a few endangered species. Instead, they discovered a treasure trove of 11 creatures never before known to science.

The team from Flora & Fauna spent from November 2023 through July 2025 exploring 60 limestone cave systems in western Cambodia. They set up cameras throughout the region to capture images of birds, mammals, and reptiles living in these unique rock formations.

Among their discoveries were three new gecko species, two millipede species, and two tiny snail species. But the star of the show is a breathtaking blue and turquoise pit viper that's still being officially confirmed as a new species.

Seven of the newly found species have already been formally described and named by scientists. The stunning viper gets its "pit" designation from a heat-sensitive organ on its head that helps it detect prey in the dark cave environments.

The Ripple Effect

These discoveries do more than just add cool animals to our wildlife catalogs. Finding new species helps scientists adjust conservation strategies worldwide and better protect ecosystems we're only beginning to understand.

The research team made another fascinating observation after identifying a striped gecko in 2024. They discovered four distinct populations of the same species evolving along different paths in the region's caves.

"Cambodia's karst areas are a treasure trove of scientific secrets waiting to be uncovered," said Sothearen Thi, the Karst Biodiversity Coordinator. From undiscovered reptiles and snails to hidden caves, these unique ecosystems continue revealing new wonders.

Evolutionary biologist Lee Grismer, who supported the survey team, emphasized why this work matters. "If we are truly going to conserve the biodiversity on this planet, we need to understand what is there," he explained.

The team's work proves a simple but powerful truth: we can't protect what we don't know exists, and every new discovery opens doors to better conservation.
