Smallest Frogs Found

Two new species of frog—each smaller than an M&M—have been discovered in Papua New Guinea.

Paedophryne dekot—dekot means “very small” in the local Daga language—is about 8.5 to 9 millimeters long. The bumpy-skinned P. verrucosa, meaning “full of warts” in Latin, is an average of 8.8 to 9.3 millimeters in length.

The previous tiny title holders, also frogs in the Paedophyrne genus, were about ten millimeters long.

Not only are the newfound frogs the smallest known in the world, they’re also the smallest tetrapods, or vertebrates with four legs. The planet’s tiniest known vertebrate is the Southeast Asian fish species Paedocypris progenetica, with mature females measuring just 7.9 millimetres. Learn more here.
