To verify the different sounds of animals along the rivers and their tributaries in Mizoram, a study was conducted. Particularly a strange sound which is never identified. Tlâwng, Durlui, Herhse and Tuitun were explored using acoustic encounter surveys (AES). Ous study revealed that the strange sound was produced by a frog, Leptobrachium smithi. The call of the male is a good indicator of the mating season. Its tadpoles were collected and studied, and compared with specimens in Thailand.
