"Pea-Sized Frog Potentially Smallest Vertebrate"

A tiny frog species, Brachycephalus pulex, from Brazil may be the world's smallest vertebrate, with males averaging just over 7 millimeters long and females a little over 8 millimeters. New research confirmed their adult status and measured their body lengths, concluding that they are potentially the smallest extant frogs in the world, surpassing the previously-identified "tiniest frog in the world."
