HOPE – Tree Frog (DiKi Records)

Tree Frog, or Tree Toad, any of several kinds of climbing frogs or toads. Most live in trees, but some inhabit smaller plants, and a few species are ground-dwellers. Tree frogs are found in most parts of the world. They vary in length from less than one inch (2.5 cm) to more than four inches (10 cm).

Tree frogs have pads at the ends of their fingers and toes. These pads help in climbing because they are rough and are covered with a sticky secretion. Some tree frogs have claw-shaped fingers and toes, and most kinds have webbed hands, webbed feet, or both. Many tree frogs can change color, usually to match their surroundings. As winter approaches, tree frogs burrow into the humus on the forest floor. Their tissues and body fluids are protected from freezing by glycerol, a type of alcohol made in the frogs’ cells.

Tree frogs are noted for the loudness and variety of their mating calls, made only by the male. Most tree frogs lay their eggs in water. There is variety in their breeding habits, however, especially among tropical American species. Some lay their eggs on leaves overhanging water into which the tadpoles, or larvae, fall after hatching. The tadpoles of certain other species are carried from tree to stream on the back of the male frog. The female of some kinds carries her eggs in a pouch on her back where they hatch and the tadpoles remain until they metamorphose.
