Frogs, like butterflies and salamanders, have what is called a "bi-phasic life cycle." They undergo metamorphosis to grow from their larval stage, as a non-reproductive tadpole that swims ...

Some tadpoles don’t poop for the first weeks of their lives. At least, that’s the case for Eiffinger’s tree frogs (Kurixalus eiffingeri), scientists report September 22 in Ecology.

The Eiffinger's tree frog found in Japan has a unique biological adaptation: its tadpoles do not defecate during their early developmental stages to reduce the risk of contaminating their ...

This viral video shows a male African bullfrog digging a channel to rescue his tadpoles. Find out why the dads do all the parenting.

The Eiffinger's tree frog (Kurixalus eiffingeri), found on Ishigaki and Iriomote islands in Japan, has a unique biological adaptation: its tadpoles do not defecate during their early developmental ...
