They are usually brown or gray-green often darker color, brown, gray. They may vary slightly in color range, but usually matches the color of the soil or rock from its natural habitat to serve as camouflage. They are primarily nocturnal and carnivorous animals. Hyla arenicolor adult frogs range from 32-57 mm in SVL. It has rough warty skin which prevents desiccation. Webbing is well developed but does not extend to the hind leg's fifth toe. Toe pads are considerably enlarged. It is distinguished from similar species by having a dark-edged light spot beneath the eye, instead of a dark bar running through the eye. Dorsal coloration is brown to gray and randomly spotted, while ventral coloration is cream to orange-yellow. This coloration aids in its ability to camouflage. When exposed to sun, the dorsal coloration changes from being normally dark to a light gray. (Stebbins 2003).
This species occurs from western and southeastern Colorado and southern Utah, south through Arizona and western New Mexico in the USA to northern Oaxaca in Mexico. There are also isolated populations in northeastern New Mexico and the Big Bend area of western Texas. It is found from near sea level to about 3,000m asl (Stebbins, 1985).
HABITAT AND ECOLOGY
This frog requires temporary or permanent pools in rocky arid scrub and mountains. It is found in rocky canyons and along intermittent or permanent streams. It frequents arroyos in semi-arid grassland, streams in pinon-juniper and pine-oak woodlands, and tropical scrub forest (Mexico) (Stebbins, 1985). It is primarily terrestrial, and in breeds in pools along canyon-bottom streams.
LIFE HISTORY, ABUNDANCE, ACTIVITY, AND SPECIAL BEHAVIORS
Breeding period ranges from March to July but can be extended due to insufficient rainfall. (Stebbins 2003).
TRENDS AND THREATS
Overcollection from humans. It is vulnerable due to exposure while basking on rocks (Stebbins 2003).
RELATION TO HUMANS
Have been used in experiments to test the thermoregulation relating to how its skin manages water uptake (Snyder and Hammerson 1992).
POSSIBLE REASON FOR AMPHIBIANS DECLINE
Intentional mortality (over-harvesting, pet trade or collecting)
