Frogs Fit on a Fingertip: Tiny New Species Discovered in India
Some of the smallest known frogs were recently discovered following a five-year survey in India. Seven new species of
"night frogs," in the Nyctibatrachus genus, include four species that are among the tiniest frogs ever found, capable of
comfortably crouching on a thumbnail with room to spare.
Though the frogs were abundant in the survey area, their miniscule size and chirping calls ? which resemble the sounds
of insects ? enabled them to remain undetected until now, scientists wrote in a new study.
Their discovery raises the total number of known night frog species to 35, with seven species recognized as miniaturized
? smaller than 0.7 inches (18 millimeters).
The smallest of the newly described frogs ? Nyctibatrachus manalari, N. pulivijayani, N. robinmoorei and N. sabarimalai ?
measure between 0.5 and 0.6 inches (12.2 and 15.4 mm).
N. webilla and N. athirappillyensis are slightly larger than their cousins at approximately 0.7 inches and 0.8 inches respectively,
while the largest of the new finds, N. radcliffei, measured 1.5 inches (38.3 mm).
Night frogs are native to the Western Ghats mountain range, one of the world's richest biodiversity hotspots and a United Nations
Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site. The region runs parallel to India's western coast,
covering an area measuring approximately 54,054 square miles (140,000 square kilometers).
