Generally, frogs lay eggs and some frog species give birth to froglets. But now, a new species of frogs has been discovered which does not lay eggs or give birth to froglets, but gives birth to live tadpoles. This is the only known frog to do so, researchers say.
This species of fanged frog is found on Sulawesi Island in Indonesia, and zoologists have been tracking for decades because they suspected it would show this unique behavior. An international team has now described the species in a study published in the journal Plos One.
