FAMILY HYLIDAE (TREE FROGS)
This family includes all the well-known 'tree frogs'. Most species have large 'suction' pads, which enable efficient climbing of most things including glass windows.
Species range in form from agile climbers to ground dwellers with reduced 'suction pads', and even burrowers which only have remnant 'suction pads'. Most species are found in warm and moist areas, but this family is found Australia wide.
'Tree frogs' occur throughout most parts of the world. Most, if not all species lay eggs, which hatch into free swimming tadpoles, which subsequently turn into frogs.
The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
