The Panamanian golden frog (Atelopus zeteki) is critically endangered. The toad is endemic to Panama and inhabits tropical forest regions, on mountains and near streams.
At one time, it was thought to have become extinct, but this little fellow can be found at the El Nispero Zoo in Valle de Anton about 70 miles from Panama City.
These frogs are not really frogs. They are toads. They are unusual because they communicate by waving at rivals and prospective mates. Frogs and toads are supposed to communicate by croaking. Some think these fellows learned to wave because of the noise of the fast-moving streams. In other words, croaks couldn’t be heard.
