A frog species that appears to be the world's smallest has been discovered in Papua New Guinea by a U.S.-based team, BBC reported.
At 7mm long, Paedophryne amauensis may be the world's smallest vertebrate. U.S. scientists suggest the frogs' tiny scale is linked to their habitat in leaf litter on the forest floor.
The frogs have evolved calls resembling those of insects, making them hard to spot.
They eat incredibly small insects and are probably prey for a large number of relatively small invertebrates that don't usually prey on frogs. Predators may well include scorpions.
