Pool frogs are extremely variable in color. In some areas they are predominantly brown with dark brown or black irregular blotches over their backs and a lighter, often yellow, dorsal stripe. In other regions they are predominantly green although the markings are similar.
Adults can grow up to 9 cm in length but males are significantly smaller. During the breeding season the males have a loud call generated by paired inflatable pouches (vocal sacs) each side of the mouth.
Unusually for frogs, pool frogs will bask in the sunshine on even the hottest of days. This is usually at the edge of pools and they are often detected by a fleeting glimpse as they dive into the water to take refuge. Thus, one needs patience and luck for a decent close shot.
