Paedophryne is a genus of microhylid frogs from Papua New Guinea. All six species known so far are amongst the smallest frog and vertebrate species.[1]

Paedophryne amauensis[change | change source]

Paedophryne amauensis is a recently discovered species of frog from Papua New Guinea. Only 7.7 millimetres (0.30 in) long, it is the world's smallest known vertebrate.[1][2][3]

Discovery[change | change source]

The frog species was discovered in August of 2009 by Christopher Austin when exploring Papua New Guinea.[1] The National Science Foundation sponsored the exploration.[4]

Characteristics[change | change source]

The frog is a millimeter smaller than the previous record holder for being the world's smallest vertebrate – a species of carp (Paedocypris progenetica) from Indonesia.[4][5] The frog mainly lives on land. According to its discoverers, the life cycle of the frog does not include a tadpole stage.[4]
