First discovered in the year 1994, the Aussie Sunset Frog (Spicospina flammocaerulea) is a species of ground-dwelling frog native to south-west Western Australia, Australia.[1] It is the only species in the genus Spicospina. It is known from only 27 sites, all occurring east and northeast of Walpole.
Description
Spicospina flammocaerulea is a smaller species, with a snout-vent length of 31-36 in the females and males growing to 29.5-34.8 mm. The physical appearance and colouration differs greatly from all other Australian frog species. It is a dark-purple to black or very dark grey on the dorsal surface. There are orange markings below the vent, around the margins of the body and on the hands and feet. The throat, chest and the underside of the hands and feet are also orange. The back is granular with lots of raised glands, a large parotoid gland is located behind each eye. The belly has vivid light blue spotting on a dark background which is smooth. The fingers and toes are free from webbing and pads.
Ecology and behaviour
The Sunset Frog is only found in isolated permanently moist peat swamps, in high rainfall areas. These sites have high moisture content and are often protected from drier conditions by seepages that provide water even through the drier seasons (Spring and Summer). Males call between October and December from shallow pools, water seepages or in open water along creek margins. They make a rapidly repeated "dd-duk-duk". Females lay less than 200 eggs that are deposited singly often supported by algae mats just below the surface of the water.
Conservation efforts
On the 19th of December 2011, the DEC in combination with Perth Zoo released 31 captive-bred endangered sunset frogs and 251 tadpoles into a private property in Mt Frankland area in order to extend the known range of the species.
