A frog that gives birth to tadpoles!


Limnonectes larvaepartus (adult female)

The Indonesian frog Limnonectes larvaepartus, formally described last year, gives birth to live tadpoles. It is the only frog to do so – the overwhelming majority of frogs lay eggs (and a handful give birth to tiny froglets). A recent paper by Mirza Kusrini, Jodi Rowley, Luna Khairunnisa, Glenn Shea, and Ronald Altig describes the reproductive biology of this unusual frog in more detail (the photos above and below are from the paper). This post from the Australian Museum has more details.

In biology, every rule seems to have exceptions! And the unusual is always waiting around the corner, ready to be discovered – especially in the world’s tropical forests.
