With voices hardly louder than an insect's buzz, the tiniest frogs ever discovered are smaller than a coin and hop about the rainforest of the tropical island of Papua New Guinea, US scientists say.

Not only are Paedophryne amauensis and Paedophryne swiftorum the smallest frogs known to man, they are also the smallest vertebrates, said the report in the science journal PLoS ONE.

The little land frog Paedophryne amauensis comes in at 7.7mm. The Paedophryne swiftorum measures a bit over 8mm.

Previously the smallest vertebrate was believed to be a transparent Indonesian fish known as Paedocypris progenetica, averaging 8mm.
