Black and white, with the pattern varying across its range. The back of its neck, upper tail and shoulders (on its wings) are white in males and grey in females, and (across most of Australia) the rest of its body is black. In south-eastern, central and south-western Australia, including Tasmania, its back and rump are entirely white. Its eye is red-brown. Young birds are usually grey rather than black and have dark eyes.

  • Eastern Bobtail (Tiliqua rugosa aspera) Similar to western bobtail but with a darker belly, larger body scales and a shorter fatter tail
  • Western Bobtail (Tiliqua rugosa rugosa) Similar to eastern and northern but paler belly and longer tail, larger ear and pale irregular bands on the back
  • Rottnest Island Bobtail (Tiliqua rugosa konowi) Yellow belly.
  • Northern Bobtail (Tiliqua rugosa palarra) Similar to western bobtail with a smaller ear and usually no pale irregular bands on the back

The caterpillar (larva) is initially pale yellow with fine hairs, before turning green. It has narrow yellow lines on its body which are sometimes hard to see. The upper side of the butterfly (adult) is white with a black tip on its forewing (front wing) and a black patch on the front edge of its hindwing. A male has one black spot on its forewing, while a female has two black spots. Looking from underneath, the forewing is white with two black spots and the hindwing is yellow.

Size

Caterpillar about 3.5 cm; Butterfly up to 5 cm wingspan.

The moaning frog is a burrowing frog native to south-western Western Australia. This frog is quite rotund, with a large head and bulbous eyes.

Brown or slate back with irregular yellow patches. Males have large limbs but show no distinguishing sexual features.

Tadpoles

Densely mottled with black and gold. Have a red or gold vertebral stripe and curved lateral line.

The motorbike frog is a ground-dwelling tree frog found in Southwest Australia. It gets its name from the male frog's mating call, which sounds like a motorbike riding past and changing gears. Other common names are Moore's frog, the western bell frog, western green and golden bell frog, and western green tree frog.

Back is green with gold mottling (after basking in sunlight). Can be almost dark brown in colder conditions. The underside usually ranges from very pale green to light brown.

The Oblong turtle (Chelodina oblonga) occurs in Northern WA and the Northern Territory. This species is also known as Southwestern snaked-neck turtle (Chelodina colliei) in southwest Western Australia.

The original specimen collected and given the name Chelodina oblonga is now thought to be from a species of long necked turtle found in northern WA and the Northern Territory, the Northern Long-necked turtle (Macrochelodina rugosa). The first specimen of the oblong turtle seen in southwest WA was originally classified as Chelodina colliei.

The carapace (upper shell) ranges in color from light brown to black. The olive to gray neck is thick, with blunt rounded tubercles. The head is large and flat with a protruding snout and an unnotched upper jaw.

Size

Adult Shell 30 - 40 cm long.

A colourful bird, the upper part of its back is bright green, merging to light blue on the lower part to its rump. Its tail is black, tinged with blue, and has two long central feathers (called streamers) that extend beyond the tip of the tail. Its forehead is blue-green and the top of its head is golden. A bold black eye-stripe runs from the base of its beak and is bordered below by a narrow blue line. Its chin is yellow, changing to chestnut on its throat, below which is a broad black band. It has a green breast, becoming paler on the belly and changing to light blue from the lower belly to the vent. It has a long, slim, curved black beak and its legs and feet are grey-black.
Young birds are generally duller and greener. They lack the black band across the lower throat and the long tail streamers.

Distinctive feature

The sexes differ in the length of their tail streamers: the male has longer, more slender streamers.

The male is unmistakable in full breeding varying from cobalt-blue in the east of its range to violet-blue in the west with a pale blue head. Wings and long tail are brown with a blue wash. In non-breeding plumage, called eclipse, he is very similar to the female, being pale brown above and white underneath although he retains the blue wash on wings and tail. The young look like the females.
