Slender Tree Frog
This common frog in the Perth region generally has a uniform back colour ranging from pale fawn to bright green. A bold dark stripe is present along both sides of the head and body. The back of the thigh is black with a mottling of bright yellow or red spots. The toes are webbed and the ends of fingers and toes have dilated discs. Maximum length is about 4.5 cm.
Breeding is limited to winter and early spring even though this species may be heard calling all year round. Males call from elevated perches or from the base of dense vegetation (usually sedges or bulrushes) surrounding lakes, swamps and watercourses.
A loud single grating 'grrrk'. Choruses can be very noisy when many males call together.
Eggs are laid in small clusters and are attached to the stems of aquatic vegetation just below the surface of the water.
The body is a pale brown with two pale stripes on each side of the body extending from the nostril and onto the tail. They have a bluntly rounded snout, the eyes are set to the side and tail fins are very deep. There are 2 upper and 3 lower rows of labial teeth. Maximum length is 5.5 cm.
The slender tree frog is one of our most distinctive frogs - it has no close relatives elsewhere in Australia and is found only in the southwest of Western Australia. It is probably an ancient survivor of wetter, earlier times in the history of the southwestern environment.
