Lesser spot-nosed monkey

Lesser spot-nosed monkey 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 Lesser spot-nosed monkey rather than just read about it. In short: The lesser spot-nosed monkey (Cercopithecus petaurista), also known as the lesser spot-nosed guenon, lesser white-nosed guenon, or lesser white-nosed monkey, is a species of primate in the family Cercopithecidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, Togo, Guinea-Bissau, and possibly Senegal.

Key takeaways

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

Reference excerpt

The lesser spot-nosed monkey (Cercopithecus petaurista), also known as the lesser spot-nosed guenon, lesser white-nosed guenon, or lesser white-nosed monkey, is a species of primate in the family Cercopithecidae. It is found in Ivory Coast, Ghana, Guinea, Liberia, Sierra Leone, Togo, Guinea-Bissau, and possibly Senegal.

Description The lesser spot-nosed monkey is a small arboreal species with a long tail. Its face is black with a white spot above its nose. A white stripe extends from the temple to below the ear. The fur of the crown, back, outer side of the limbs and upper surface of the tail are olive-green or khaki. In some forms, the middle and lower back have a reddish tinge. The individual hairs, especially on the crown, are flecked with black and yellow. The underparts, inner side of the limbs and underside of the tail are white or cream.

Distribution and habitat The species is found in West Africa. Its range includes Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana and Togo, and it has also been recorded in southeastern Senegal. It is adaptable and is found in a range of habitats including primary and secondary forests, gallery forests, regenerating felled areas, coastal scrubland, bushy areas along farmland, and cultivated fields.

Ecology The lesser spot-nosed monkey is diurnal, arboreal and cryptic; it moves through the forest cautiously, seldom climbing to the high canopy but mostly frequenting the understorey layers and lianas. It forms social groups of about ten members: usually one adult male, several adult females and their young. It feeds on leaves, fruit, flowers and insects, gathering its food and storing it in cheek pouches; when these are full, they are prominent, its white throat resembling a snowball. The reproduction of this species has been seldom studied. Females give birth to a single young after a gestation period of about seven months. Breeding does not appear to be seasonal.

Status C. petaurista is a common and adaptable species. Some areas of forest in which it lives are being degraded but it is tolerant of the disturbance. It may be hunted for bushmeat in some areas, but the International Union for Conservation of Nature has not identified any major threats and has assessed its conservation status as being near-threatened.

Worked examples

Example 1 — a first encounter with Lesser spot-nosed monkey

Start with the simplest possible case. Write down what Lesser spot-nosed monkey 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 Lesser spot-nosed monkey 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 Lesser spot-nosed monkey 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 Lesser spot-nosed monkey

In research: Lesser spot-nosed monkey 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 Lesser spot-nosed monkey 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: Lesser spot-nosed monkey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Guenons, IUCN Red List near threatened species, so understanding it makes those chapters shorter.
In everyday life: Look for Lesser spot-nosed monkey 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.
