Frog Poison

This is a great video that I found about poison found in frogs.  

World's Smallest Frog Found

The world's smallest known vertebrate is a frog the size of a housefly, a new study says.

At an average of 7.7 millimeters long, the newfound Paedophryne amauensis is a hair smaller than the previous record holder, the Southeast Asian fishspecies Paedocypris progenetica, whose females measure about 7.9 millimeters.

During recent field surveys in southern Papua New Guinea, scientists found P. amauensis and  another new species of tiny frog, Paedophryne swiftorum, which measures about 8.6 millimeters.

"I think it's amazing that they're continuing to find smaller and smaller frogs," said Robin Moore, an amphibian expert with Conservation International, who was not involved in the study.

It's obvious "they're adapting to fill a niche that nothing else is filling," he said.

Indeed, the frogs likely evolved their tiny sizes to eat tiny invertebrates, such as mites, that are ignored by bigger predators, said study co-author Christopher Austin, a biologist at Louisiana State University in Baton Rouge.

Tiny Frogs Hard to Catch

Discovered in 2010 but announced on Wednesday, all the species of the Paedophyrne genus are tiny and seem to live solely amid leaf litter on New Guinea's rain forest floor.
