Cliffy Stream Frog

The Cliffy Stream Frog, Litoria phyllochroa, is a small, slender tree frog in the family Hylidae endemic to southeastern Australia, occurring in New South Wales and Victoria. It inhabits fast-flowing, rocky streams in forested gorges, cliff-sided creek valleys, and the rocky stream courses of the Great Dividing Range and adjacent ranges. The species is well adapted to the rocky stream environment, clinging to moist cliff faces and boulders using enlarged toe pads and spending much of its time on wet, vertical surfaces near cascades and fast riffles. Adults are relatively small, typically 30–40 mm in length, and are greenish-brown above with a pale lateral stripe, blending into the rocky, mossy stream substrate. Males call from rocky perches near the water's edge, producing a repeated clicking or ticking call. The species breeds in fast-flowing sections of mountain streams, with tadpoles adapted to strong currents through enlarged oral suckers. Stream frogs in Australia have been severely affected by chytridiomycosis, a fungal disease caused by Batrachochytrium dendrobatidis, which has driven many mountain stream species to extinction or severe decline. Litoria phyllochroa is currently listed as Least Concern but faces ongoing threats from disease, drought, and climate change affecting streamflow in the ranges.

Noctule

Noctule (Nyctalus noctula) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.
