The NYTimes reports on a new discovery of a frog that gives birth to live tadpoles:
A tiny frog discovered in the rain forests of Indonesia’s Sulawesi Island is the only frog known to give birth to live tadpoles.
Of the roughly 6,000 frogs known in the world, about a dozen species fertilize their eggs internally. A handful give birth to froglets, and a few lay fertilized eggs.
The newly described frog, named Limnonectes larvaepartus, was first discovered in 1998 by Djoko Iskandar, a zoologist at the Bandung Institute of Technology in Indonesia. The frog weighs just two-tenths of an ounce, or about as much as a nickel. At the time, Dr. Iskandar noticed that the frogs appeared to be laying tadpoles, but he was not able to identify the species.
