Golden-faced saki

Golden-faced saki 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 Golden-faced saki rather than just read about it. In short: The golden-faced saki (Pithecia chrysocephala) is a species of saki monkey, a type of New World monkey. It is found in Brazil north of the Amazon, on both sides of the Rio Negro.

Key takeaways

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

Reference excerpt

The golden-faced saki (Pithecia chrysocephala) is a species of saki monkey, a type of New World monkey. It is found in Brazil north of the Amazon, on both sides of the Rio Negro. This species was formerly considered a subspecies of the white-faced saki (P. pithecia), but was raised to full species status in 2014. The species is named for the coloration of the male, which has black body hair but orange or red-brown facial hair. The female has lighter body color and more bare skin on the face, with lines of orange hair extending down from below the eyes around the snout, as well as orange ventral fur. The golden-faced saki features a smaller, less prognathic, and less spherical cranial vault than the white-faced saki.

Worked examples

Example 1 — a first encounter with Golden-faced saki

Start with the simplest possible case. Write down what Golden-faced saki 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 Golden-faced saki 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 Golden-faced saki 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 Golden-faced saki

In research: Golden-faced saki 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 Golden-faced saki 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: Golden-faced saki is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Endemic mammals of Brazil, Fauna of the Amazon, so understanding it makes those chapters shorter.
In everyday life: Look for Golden-faced saki 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.
