Tiny Brazilian Flea Toad Might Be the World’s Smallest Vertebrate According to Scientists
Can you picture an animal small enough to comfortably sit atop your fingernail? It may sound like work of fiction, but such an animal actually exists—the Brazilian flea toad. Don't be fooled by the name though. It is neither a flea nor a toad, but, in fact, a frog. Due to its size, it is believed to be the smallest amphibian and smallest vertebrate in the world.
