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 Taman Negara National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 17 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Blue-eyed Anglehead Lizard in Taman Negara National Park on a given day, against under 5% in March–April, July–August and October–January, 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 Taman Negara National Park, in our data
Taman Negara National Park is the only park 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.
Same family: Agamidae
The closest relatives of the Blue-eyed Anglehead Lizard that you can see in Taman Negara National Park (family Agamidae, Dragons) are Dusky Earless Agama (about 40%) and Green Crested Lizard (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-eyed Anglehead Lizard is recorded against all the reptiles logged in Taman Negara National Park (8 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.
