Here is where you can learn all about Frogs. Frogs are cool little critters. You'd be amazed at the number of species of frogs and the fact that there are still species being discovered all over the world.

The most recent frog discovery was made in a remote region of Columbia, in August 2007. The frog is being called at this time, the golden frog of Supatá. This frog is approximately 2 centimeters in length and is yellowish in color. It's really quite a pretty little frog. They believe this frog is poisonous. Scientists believe this frog is part of a group of very venomous frogs called "dart frogs". They really don't much about this frog yet, as they only place this frog resides is in the remote area of Columbia on about a 50 acre area.
