A spectacular blue snake is one of 11 new species that has been discovered in caves in Cambodia.
The turquoise pit viper was collected during a large survey of the unique caves that make up the landscape in western Cambodia.
While its official name has not been decided, the “pit” refers to the heat-sensitive organ on its head, which it uses to detect prey.
The survey team, led by the wildlife conservation charity Fauna & Flora, explored more than 60 caves across 10 hills in Battambang province, western Cambodia.
They also discovered other species that are new to science, including a flying snake, several geckos, two micro-snails and two millipedes.
