Spotted paddle-tail newt
"Pachytriton" species are stout-bodied, smooth-skinned aquatic newts. Their heads are large and flattened, and they have conspicuous labial folds and short, stubby legs and toes. They breathe through both lungs and skin. 
"P. brevipes" ranges from 5.5 to 7.5 in as an adult. It has prominent labial folds, long digits, and smooth skin, which differs from the tuberculate skin typical of newts.
Smooth newt
Smooth newts are generalist carnivores with a broad diet including invertebrates, crustaceans, and the eggs and hatchlings of frogs and fish. Therefore, they are likely to prey on and compete for food with a wide range of Australian terrestrial and freshwater species
