Paedophryne amauensis is a species of frog from Papua New Guinea discovered in August 2009 and formally described in January 2012[1]. At 7.7 millimetres (0.30 in) in length, it is probably the world's smallest known vertebrate.[2][1]

Discovery

The frog species was discovered in August of 2009 by ecologist Christopher Austin while on an expedition to explore the diversity of Papua New Guinea, near Amau Village in the Central Province.[1] The discovery was published in the peer-reviewed scientific journal PLoS ONE in January 2012.[1]

Characteristics

P. amauensis is a millimeter smaller than the previous record holder for being the world's smallest vertebrate, a species of carp (Paedocypris progenetica) from Indonesia.[3][4] The frog lives on land, and its life cycle does not include a tadpole stage.[3] The frog is crepuscular and feeds on small invertebrates. They are capable of jumping 30 times their own body length. Males call for mates with a series of very high pitched 8400–9400 Hz insect-like peeps.[1]

Habitat

Like all species of Paedophryne known so far, Paedophryne amauensis lives in the leaf litter on the floors of tropical forests.[1]
