Gonocephalus liogaster

Gonocephalus liogaster is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gonocephalus liogaster rather than just read about it. In short: 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.

Key takeaways

Gonocephalus liogaster belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gonocephalus liogaster to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gonocephalus liogaster from memory before moving on to harder problems.

Reference excerpt

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.

Geographic range G. liogaster is found in Indonesia (Borneo, Natuna Islands, Sumatra) and Malaysia (West Malaysia).

Habitat The preferred natural habitats of G. liogaster are forest and freshwater wetlands, at altitudes of 100–400 m (330–1,310 ft).

Description 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.

Behavior G. liogaster is diurnal and arboreal.

Diet G. liogaster preys upon insects.

Reproduction 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.

Worked examples

Example 1 — a first encounter with Gonocephalus liogaster

Start with the simplest possible case. Write down what Gonocephalus liogaster claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gonocephalus liogaster before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gonocephalus liogaster ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gonocephalus liogaster

In research: Gonocephalus liogaster appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gonocephalus liogaster in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gonocephalus liogaster is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agamidae stubs, Fauna of Sumatra, Gonocephalus, so understanding it makes those chapters shorter.
In everyday life: Look for Gonocephalus liogaster outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
