Troglonectes retrodorsalis

Troglonectes retrodorsalis is a science 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 Troglonectes retrodorsalis rather than just read about it. In short: Troglonectes retrodorsalis is a species of stone loach. This cavefish is found only in Guangxi in China.

Key takeaways

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

Reference excerpt

Troglonectes retrodorsalis is a species of stone loach. This cavefish is found only in Guangxi in China. Some authorities places this species in the genus Yunnanilus or in Oreonectes. The specific name is a compound of the Latin words retro meaning back or past and dorsalis meaning "the back", referring to the placement of the dorsal fin closer to base of the caudal fin than to the tip of snout. Troglonectes retrodorsalis grows to 3.8 cm (1.5 in) standard length.

Worked examples

Example 1 — a first encounter with Troglonectes retrodorsalis

Start with the simplest possible case. Write down what Troglonectes retrodorsalis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Troglonectes retrodorsalis 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 Troglonectes retrodorsalis 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 Troglonectes retrodorsalis

In research: Troglonectes retrodorsalis appears in science 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 Troglonectes retrodorsalis 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: Troglonectes retrodorsalis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cave fish, Endemic fauna of Guangxi, Endemic fish of China, so understanding it makes those chapters shorter.
In everyday life: Look for Troglonectes retrodorsalis 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.
