McLachlan's girdled lizard

McLachlan's girdled lizard 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 McLachlan's girdled lizard rather than just read about it. In short: McLachlan's girdled lizard (Cordylus mclachlani), also known commonly as McLachlan's spiny-tailed lizard, is a species of lizard in the family Cordylidae. The species is endemic to South Africa.

Key takeaways

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

Reference excerpt

McLachlan's girdled lizard (Cordylus mclachlani), also known commonly as McLachlan's spiny-tailed lizard, is a species of lizard in the family Cordylidae. The species is endemic to South Africa.

Etymology The specific name, mclachlani, is in honor of South African herpetologist Geoffrey Roy McLachlan.

Description Adults of Cordylus mclachlani usually have a snout-to-vent length (SVL) of 5–7 cm (2.0–2.8 in). The body is very flattened. Dorsally, it is olive brown, with some dark brown and yellow spots. Ventrally, it is cream-colored.

Geographic distribution Cordylus mclachlani is found in the South African provinces of Northern Cape and Western Cape.

Habitat The preferred natural habitat of Cordylus mclachlani is rocky areas of shrubland.

Behavior Cordylus mclachlani is terrestrial and rupicolous (rock-dwelling), sheltering in narrow crevices.

Reproduction Cordylus mclachlani is ovoviviparous.

Worked examples

Example 1 — a first encounter with McLachlan's girdled lizard

Start with the simplest possible case. Write down what McLachlan's girdled lizard 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 McLachlan's girdled lizard 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 McLachlan's girdled lizard 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 McLachlan's girdled lizard

In research: McLachlan's girdled lizard 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 McLachlan's girdled lizard 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: McLachlan's girdled lizard is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cordylus, IUCN Red List least concern species, Lizard stubs, so understanding it makes those chapters shorter.
In everyday life: Look for McLachlan's girdled lizard 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.
