Ctenophorus decresii, also known commonly as the tawny dragon, tawny crevice-dragon, or tawny rock dragon, is a species of lizard in the family Agamidae. The species is endemic to Australia. C. decresii is known for its variations in throat colours which change based on environmental conditions. Its primary food sources consist of both vegetation and invertebrates, and it prefers to live in rocky habitats. The average snout-to-vent length (SVL) of the species is 80.76 mm (3.180 in), with larger individuals being around 89 mm (3.5 in) and smaller individuals around 72 mm (2.8 in). The optimal time for mating in this species is two to three weeks after the females emerge from hibernation. Eggs are typically laid from September to October with most of them being laid earlier in the period.
C. decresii is a member of the genus Ctenophorus, which is a very diverse group of lizards found throughout Australia. The specific name, decresii, refers to L'Île de Decrès, which was the French name for Kangaroo Island in 1837. The usual common names for the species are tawny dragon, tawny crevice-dragon, and tawny rock dragon.

No species of the same family or order lives in Flinders Chase, so these are its closest relatives here: other reptiles.
Likely
About 50% of wildlife watchers report a Tawny Crevice-dragon sighting in Flinders Chase on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
November
In that month about 70% of wildlife watchers report a Tawny Crevice-dragon in Flinders Chase on a given day, against about 10% in May to July, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Tawny Crevice-dragon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Flinders Chase, in our data
Flinders Chase is the only park on Wallace's Line with enough records to rate Tawny Crevice-dragon sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tawny Crevice-dragon is recorded against all the reptiles logged in Flinders Chase (44 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
