extinction date: 2008 (?)

Like so many other amphibian species also Bob's Robber Frog is now feared to be extinct due to Chytridiomycosis, a disease caused by the fungus Batrochochytrium dendrobatidis, that infects almost every amphibian species all over the world. In most cases not much is known about the live of these amphibians, because whole populations disappear completely just very shortly after beeing discovered by scientists.


Bob's Robber Frog was endemic to the Omar Torrijos National Park in Panama, an region that was the place for a long term study starting in the year 1998. During that time seventy four frog species were identified in that region, eleven of them new to science. It was in the year 2002, when the fist dead frogs were found, all of them killed by the Chytridiomycosis fungal disease.


Another name for this frog is/was Streamside Rain Frog, which indicates that this species was found near streams. It is also known that in frogs of the genus Craugastor the complete metamorphosis occures within the eggs and therefore the young hatch fully developed.

Bob's Robber Frog was seen for the last time in the year 2008.
