Frogs and other amphibians lay eggs, but mammals give birth to live young, right?
A newly described species of frog gives birth to live tadpoles, and is the only known frog to do so, researchers say.
The discovery happened one night last summer, when researcher Jim McGuire was tromping through the rainforest in Sulawesi, an Indonesian island east of Borneo. McGuire stumbled across what looked like a single male frog. But when he reached out to grab it, he found himself holding much more, said McGuire, a herpetologist at the University of California, Berkeley.
“As soon as I picked her up, she squirted tadpoles all over my hand,” McGuire told Live Science. He didn’t have time to take a video of the frog giving birth, but did find more tadpoles in nearby pools. The find “was clear indication” that the females do in fact give birth to live tadpoles, he said.
