Treefrog Family

Hylidae

Treefrogs are adapted for an arboreal existence with toe tips that are expanded into sticky adhesive pads used in climbing, and long slender limbs and digits that help them cling to twigs and bark.  Color and pattern changes are evident in some species, with individuals changing from gray to green to brown or from patterned to plain-colored depending on environmental conditions.  Treefrogs can be found in a variety of habitats, including swamps, moist woodlands, and brushy thickets.

Male treefrogs typically call while perched in vegetation over, near, or in water.   When a female approaches, a male clasps her behind the forelimbs and the amplectant pair goes to the water to lay egg masses.
