Florida Bog Frog

It took the combined scrutiny of Jake and me to find this adult male bog frog in its grassy home. In 1985 the Florida bog frog, Rana okaloosae, Florida’s smallest ranid frog was described by Paul Moler. Adult at about 2” svl, because of its unique call (a repetitive single note) this tiny greenish ranid was found in a small creek on Eglin AFB in 1982 by Moler. It is known from a few dozen small populations in Santa Rosa, Okaloosa, and Walton counties. Florida. In overall appearance the bog frog is quite similar to the common and widespread bronze frog, Rana clamitans. However from the latter the bog frog differs in having very reduced webbing on the hind feet, lacking a central raised area on the tympani, and the dorsolateral folds, lighter in color than the dorsum, terminate just posterior to the sacral hump. Since all other ranid frogs are considerably bigger than the bog frog when adult, size can also be an identifying factor. It had been about 10 years since I had last looked this little frog up, but with the help of Paul Moler, and the calling of the frogs, Jake and I were able to find a small population and update our photos. Thanks, Paul.
The bog frog is a Florida endemic.
Slow flowing creeks with heavily overgrown banks and emergents are the home of the bog frog.
