Gonocephalus liogaster, also known commonly as the blue-eyed anglehead lizard, the orange-ringed anglehead lizard, and the tropical forest dragon, is a species of lizard in the family Agamidae. The species is native to Southeast Asia.
G. liogaster is found in Indonesia (Borneo, Natuna Islands, Sumatra) and Malaysia (West Malaysia). The preferred natural habitats of G. liogaster are forest and freshwater wetlands, at altitudes of 100–400 m (330–1,310 ft).
A large and robust lizard, G. liogaster may attain a snout-to-vent length (SVL) of 14 cm (5.5 in), plus a tail length of 31.5 cm (12.4 in). The tail is laterally compressed, and all four legs are long. The iris of the eye is blue in males, but brown in females.
G. liogaster is diurnal and arboreal. G. liogaster preys upon insects. G. liogaster is oviparous. Clutch size is usually three eggs, but may be as few as one or as many as four. Each egg measures 23 mm × 11 mm (0.91 in × 0.43 in). After a period of about 100 days, the eggs hatch in August.

Possible
About 20% of wildlife watchers report a Blue-eyed Anglehead Lizard sighting in Kuching on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report a Blue-eyed Anglehead Lizard in Kuching on a given day, against under 5% in January–March, June–July and September–November, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Blue-eyed Anglehead Lizard sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Kuching, in our data
Kuching is the only city on Wallace's Line with enough records to rate Blue-eyed Anglehead Lizard sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blue-eyed Anglehead Lizard is recorded against all the reptiles logged in Kuching (9 verified sightings), 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.
