Reference excerpt

Pseudophilautus adspersus is an extinct species of frog in the family Rhacophoridae. It was endemic to Sri Lanka.

Description Females 33.3–41.7 mm. Head flattened dorsally. Tympanum described as distinct by Günther (1872) but outer rim is not discernible in preserved holotype. Prominent supratympanic fold. Snout angled at 105 degrees, laterally truncated, with sharp canthi and flattened loreal region and internarial region. Vomerine teeth and lingual papilla are absent. Calcar lacking. Supernumerary tubercles on both palm and sole. Fingers have lateral dermal fringe but lack webbing. Medially webbed toes. No tarsal fold. Warty skin texture on anterior dorsum, while the posterior dorsum is smooth. Dorsal forelimb has glandular warts. Smooth granular skin on throat and underside of thigh, and rough granular skin on chest and belly. Flanks and feet are granular (Manamendra-Arachchi and Pethiyagoda 2005).

Distribution and habitat Pseudophilautus adspersus was endemic to Sri Lanka. The holotype has the non-specific type locality "Ceylon", while the second specimen was collected at Nuwara Eliya, a resort town and tea-growing area at 1,700–2,500 m in the central mountainous region of Sri Lanka (Manamendra-Arachchi and Pethiyagoda 2005). The exact habitat that this species required is not known (Stuart et al. 2008).

Worked examples

Example 1 — a first encounter with Pseudophilautus adspersus

Start with the simplest possible case. Write down what Pseudophilautus adspersus 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 Pseudophilautus adspersus 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 Pseudophilautus adspersus 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 Pseudophilautus adspersus

In research: Pseudophilautus adspersus 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 Pseudophilautus adspersus 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: Pseudophilautus adspersus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibian extinctions since 1500, Amphibians described in 1872, Endemic amphibians of Sri Lanka, so understanding it makes those chapters shorter.
In everyday life: Look for Pseudophilautus adspersus 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.
