Long-finned pike

Long-finned pike 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 Long-finned pike rather than just read about it. In short: The long-finned pike or yellowfin pike (Dinolestes lewini) is a species of acropomatiform ray-finned fish, the only species in the genus Dinolestes, as well as the family Dinolestidae. It is an elongated fish with a pointed snout, and silver in color, similar in appearance to a barracuda, and grows up to 84 cm (33 in) in total length.

Key takeaways

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

Reference excerpt

The long-finned pike or yellowfin pike (Dinolestes lewini) is a species of acropomatiform ray-finned fish, the only species in the genus Dinolestes, as well as the family Dinolestidae. It is an elongated fish with a pointed snout, and silver in color, similar in appearance to a barracuda, and grows up to 84 cm (33 in) in total length. It is endemic to the coastal waters of southern Australia, including New South Wales, at depths between 5 and 65 m (16 and 213 ft).

Worked examples

Example 1 — a first encounter with Long-finned pike

Start with the simplest possible case. Write down what Long-finned pike 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 Long-finned pike 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 Long-finned pike 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 Long-finned pike

In research: Long-finned pike 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 Long-finned pike 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: Long-finned pike is common in secondary-school and first-year university syllabi. It links to neighbouring topics Acropomatiformes, Acropomatiformes stubs, Fish common names, so understanding it makes those chapters shorter.
In everyday life: Look for Long-finned pike 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.
