Biologists from Delhi University discovered this darling frog that when fully grown is just 0.3937 inches or 10 mm. From Loren Coleman's post at Cryptomundo:
Delhi University Systematics Biologist S. D. Biju and his colleagues have found this new frog, India's smallest land vertebrate, in the Western Ghats of Kerala, a mountainous region in the western portion of India.
The humid rainforests of the Western Ghats are the perfect habitat for these nocturnal frogs, which enjoy making mating calls from under leaf litter and among the roots of ferns during the monsoon months.
