Sailback houndshark

Sailback houndshark 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 Sailback houndshark rather than just read about it. In short: The sailback houndshark (Gogolia filewoodi) is a houndshark of the family Triakidae, and the only member of the genus Gogolia. It is found in the deep waters of continental shelf off northern Papua New Guinea.

Key takeaways

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

Reference excerpt

The sailback houndshark (Gogolia filewoodi) is a houndshark of the family Triakidae, and the only member of the genus Gogolia. It is found in the deep waters of continental shelf off northern Papua New Guinea. Only one specimen has been found, at a depth of 73 m (240 ft). It measured 74 cm (29 in) in length. The reproduction of this shark is ovoviviparous.

Worked examples

Example 1 — a first encounter with Sailback houndshark

Start with the simplest possible case. Write down what Sailback houndshark 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 Sailback houndshark 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 Sailback houndshark 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 Sailback houndshark

In research: Sailback houndshark 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 Sailback houndshark 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: Sailback houndshark is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic fauna of Papua New Guinea, Fish described in 1973, Fish of Papua New Guinea, so understanding it makes those chapters shorter.
In everyday life: Look for Sailback houndshark 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.
