This amphibian is certainly “home, home on the range, where the Sears and the Frigidaire play!”. This is the Range Frog of the American southwest, largest of all the anurans. Whereas the great American Bullfrog may reach lengths of just slightly over 6”, the Range Frog can grow to 38” in length (42” or more, with grill-top).

The Range Frog’s dense and polished white surface is an evolutionary adaptation that reflects most of the intense heat of the desert sun (and also resists those messy spills and stains). An internal thermostat controls the Frog’s overall heat gain, as well as its distribution back to its radiating eyes and innards.

Since the creature’s prime habitat is an irregular plain of dirt, sand, rocks and boulders, occasionally gully-carved by flash rainstorms, the Range Frog has also evolved leveling feet.

There are those that variously speculate that the vocalizations of the Range Frog are similar to the ‘ribbit-ribbit’, ‘jug o’ rum’, ‘croak’, or ‘brekekekekoax’ of other frog species. However, scientists have recently documented that the Range Frog instead emits more of a ‘tick-tick-tick-fwoom!-hiss’.

Here we see a prime Range Frog with one of its smaller evolutionary cousins, the Pilot Lizard.
