Small enough to fit on a fingernail, this amphibian is among several previously unknown salamanders recently discovered in Costa Rica, scientists announced on January 4, 2008.

The species, which has yet to be named, measures just 1.18 inches (3 centimeters) long and lives among tree mosses and dead leaves on the forest floor of La Amistad National Park.

The species is the seventh dwarf salamander in the genus Nototriton found in Costa Rica, a species-diversity hot spot for the moisture-loving creatures.

Finding so many new species in one area is exciting, particularly as this is probably the only place in the world you can find these animals, said Alex Monro of London's Natural History Museum.
