Reference excerpt

Marmosops pakaraimae, the Pantepui slender opossum, is a species of opossum within the genus Marmosops.

Distribution Marmosops pakaraimae is known from five localities, with three in the Pakaraima Highlands of western Guyana and two in adjacent highlands of eastern Venezuela. Recorded elevations at these localities range from 800 to approximately 1500 m above sea level. Marmosops pakaraimae is one of only seven mammalian species known to be endemic to the Pantepui region. While the endemic flora and avian fauna of this area have been relatively well-studied, mammalian endemism remains limited. Prior to the description of Marmosops pakaraimae, the only didelphid marsupials known to be restricted to the region were Marmosa tyleriana and Monodelphis reigi.

Description Marmosops pakaraimae is a small species within the genus Marmosops, exhibiting all diagnostic qualitative traits typical of the genus. The body pelage is dark brown (near dark umber) dorsally, with indistinctly paler lateral coloration and a superficially whitish ventral side. The hairs of the throat, chest, and abdomen are uniformly gray-based, with self-white fur limited to the apex of the chin, oral margins, and scrotum. Marmosops pakaraimae's long tail is substantially longer than the combined length of the head and body (mean LT/HBL × 100 = 150%). It possesses long nasal bones that are wider posteriorly than anteriorly, a very broad interorbital region, and rounded supraorbital margins. The species also features unique dental characteristics, including short upper canines with both anterior and posterior accessory cusps, as well as specific traits in the lower molars.

Morphological comparisons Marmosops pakaraimae averages larger than Marmosops parvidens in all measured external dimensions except ear length, with notable differences in dorsal and ventral pelage coloration. The species is also larger than Marmosops pinheiroi, with comparable differences in coloration and morphology, particularly in cranial measurements and dental characteristics.

Worked examples

Example 1 — a first encounter with Marmosops pakaraimae

Start with the simplest possible case. Write down what Marmosops pakaraimae 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 Marmosops pakaraimae 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 Marmosops pakaraimae 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 Marmosops pakaraimae

In research: Marmosops pakaraimae 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 Marmosops pakaraimae 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: Marmosops pakaraimae is common in secondary-school and first-year university syllabi. It links to neighbouring topics IUCN Red List vulnerable species, Mammals of Guyana, Mammals of Venezuela, so understanding it makes those chapters shorter.
In everyday life: Look for Marmosops pakaraimae 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.
