Peron's tree frog
species of amphibian

Peron's tree frog (Pengilleyia peronii), also known as the emerald-spotted tree frog, emerald-speckled tree frog, laughing tree frog, and maniacal cackle frog, is species of tree frog in the family Pelodryadidae. It is a common frog found in Australia.
Description and habitat
Peron's tree frog is one of the most variably coloured frogs in Australia, with the ability to change colour in less than one hour. They don't like to be handled for long periods of time. They also vary in shades of grey and brown, where their lightest is almost white. The frog has mottled yellow and black thighs, armpits, and groin. Occasionally, emerald spots are found on the back, which increase in number with age. A characteristic uncommon in the family Pelodryadidae is pupils which appear cross-shaped. This characteristic is only shared with Tyler's tree frog within the genus Pengilleyia. The male Peron's tree frog is about 44–53 mm, while females are 46–65 mm.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Peron's tree frog”, the useful work is to connect “species of amphibian” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 11, 2026. The linked authority identifier is Q2275319. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
