### Identification The Baw Baw Frog (*Philoria frosti*) is a stout, terrestrial frog measuring between 42mm and 55mm. Its dorsum is typically a dark, muddy brown or charcoal, often textured with fine warts that give it a rugged, "earthy" appearance. Look for the prominent, pale parotoid glands sitting just behind the eyes and a distinct dark stripe running from the snout through the eye to the shoulder. Unlike many aquatic frogs, their toes lack webbing. You can distinguish them from the similar Southern Toadlet by their larger size and the absence of bright orange patches in the groin.
### Habitat & Range This species is a true "sky island" specialist, found nowhere else on Earth but the sub-alpine plateau of Mount Baw Baw in Victoria, Australia. They occupy a narrow elevational band above 1,300 meters, specifically clinging to cool, permanent seepages, sphagnum bogs, and the damp leaf litter beneath Snow Gum woodlands.
### Behaviour Observing a Baw Baw Frog requires patience and a keen ear. They are largely subterranean; during the breeding season (October to December), males retreat into moist cavities or "seepage tunnels" beneath thick moss or logs. From these hidden bunkers, they emit a rhythmic, low-pitched "cluck... cluck... cluck." They are slow-moving and cryptic, relying on their camouflage to vanish into the peat.
### Diet As a generalist insectivore, *P. frosti* forages through the damp alpine humus. They primarily hunt small invertebrates, including beetles, ants, and spiders, using a "sit-and-wait" strategy within the safety of the leaf litter.
### Fascinating Fact The Baw Baw Frog exhibits a remarkable "non-feeding" larval stage. After the female lays her eggs in a foamy nest, the tadpoles hatch but never actually eat. Instead, they live entirely off their own internal yolk sacs until they metamorphose into tiny froglets!
