Meet the Smallest Frog in the World with 7.7 mm in Length

The world’s smallest frog is Paedophryne amanuensis. The smallest known vertebrate is a species of frog from Papua New Guinea with 7.7 mm (0.30 in) in length.

The vertebrate was listed in the Top 10 New Species 2013 by the International Institute for Species Exploration for discoveries made during 2012.

World’s smallest frog was discovered in August 2009 by Louisiana State University herpetologist Christopher Austin.

Where did the smallest vertebrate discovered?

The new species was found near Amau village in the Central Province, from which its specific name is derived. The discovery was published in the peer-reviewed scientific journal PLOS One in January 2012.

According to Wikipedia “P. amauensis, attaining an average body size of only 7.7 millimetres (0.30 in), is 0.2 millimetres (0.0079 in) smaller than the previous record-holder as the world’s smallest vertebrate, a species of cyprinid fish (Paedocypris progenetica; 7.9 mm [0.31 in]) from Indonesia and a species of goby fish(Schindleria brevipinguis; 7.7 mm [0.30 in]) from Australia”.

“I think it’s amazing that they’re continuing to find smaller and smaller frogs,” said Robin Moore, an amphibian expert with Conservation International, who was not involved in the study.

The frogs are so small it’s hard to see their earth-colored skin patterns with the naked eye, so Austin took pictures and then zoomed in, using a digital camera like a microscope.
