New species of fanged frog has evolved internal fertilization

Scientists have discovered a rare new species frog in Indonesia that gives birth to live tadpoles which is unlike birth method of all other frogs. It gives birth to live tadpoles instead of laying eggs.

“Almost all frogs in the world – more than 6,000 species – have external fertilization, where the male grips the female in amplexus and releases sperm as the eggs are released by the female… But there are lots of weird modifications to this standard mode of mating. This new frog is one of only 10 or 12 species that has evolved internal fertilization, and of those, it is the only one that gives birth to tadpoles as opposed to froglets or laying fertilized eggs.” –Jim McGuire, Herpetologist 

This new species of fanged frog was discovered a few decades ago but then, the frog’s mating and an actual birth had never been observed before.
