Prince Regent gudgeon

Prince Regent gudgeon 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 Prince Regent gudgeon rather than just read about it. In short: The Prince Regent gudgeon (Hypseleotris regalis) is a species of fish in the family Eleotridae endemic to Australia, where it is only known to occur in clear, rocky pools in the Prince Regent Reserve in Western Australia. This species can reach a length of 5 cm (2.0 in).

Key takeaways

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

Reference excerpt

The Prince Regent gudgeon (Hypseleotris regalis) is a species of fish in the family Eleotridae endemic to Australia, where it is only known to occur in clear, rocky pools in the Prince Regent Reserve in Western Australia. This species can reach a length of 5 cm (2.0 in).

Biology The Prince Regent gudgeon is a freshwater fish. It is known to inhabit clear, rocky pools with slow to moderate flow. Their males and females differ as the female fish are lighter colored, with their truncate fin and dorsal fin well separated. The males are larger, with a rounded caudal fin, prolonged dorsal and anal rays and the first dorsal membrane almost touching the second dorsal.

Worked examples

Example 1 — a first encounter with Prince Regent gudgeon

Start with the simplest possible case. Write down what Prince Regent gudgeon 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 Prince Regent gudgeon 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 Prince Regent gudgeon 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 Prince Regent gudgeon

In research: Prince Regent gudgeon 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 Prince Regent gudgeon 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: Prince Regent gudgeon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Eleotridae stubs, Fish described in 1982, Freshwater fish of Western Australia, so understanding it makes those chapters shorter.
In everyday life: Look for Prince Regent gudgeon 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.
