Why in the news?
- Scientists have discovered Doria’s foam-nesting tree frog after 108 years in the buffer zone of Pualreng National Park, Mizoram.
- Doria’s foam-nesting tree frog (Chirixalus doriae) was first described in 1893 from Karin Bia-po in Myanmar and was later sighted in Thailand, Laos, Cambodia, Vietnam and Bangladesh.
- It was last recorded in 1912 in Arunachal Pradesh, after which it was not sighted in India.
- This frog derives its name from the secretion of foam for covering the eggs laid by females. The foam guards the eggs against predators, direct sunlight and desiccation,
- It belongs to the family of frogs which have the presence of opposable fingers.
- Scientists are focussing on further sampling for more specimens and genetic data of this species which would be necessary to illuminate the population status of the species in the region.
