Jack Garrick 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 Jack Garrick rather than just read about it. In short: John Andrew Frank Garrick (24 March 1928 – 30 August 2018) was a New Zealand ichthyologist. Career Garrick specialised in elasmobranchs and published many books and articles about shark and ray biology.

Key takeaways

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

Reference excerpt

John Andrew Frank Garrick (24 March 1928 – 30 August 2018) was a New Zealand ichthyologist.

Career Garrick specialised in elasmobranchs and published many books and articles about shark and ray biology. In 1982, he published a thorough taxonomy on sharks of the genus Carcharhinus, where he identified the smoothtooth blacktip shark as a new species. He is the species authority for several types of sharks, including the New Zealand lanternshark. Garrick was a zoology professor at Victoria University of Wellington, appointed to a personal chair in 1971. Garrick had a primary interest in the taxonomy of sharks and rays, and carried out the first exploratory deep-sea sampling using specially adapted cone nets, baited traps, and longlines, regularly to depths greater than 2000 metres. Many new and rare species were obtained by use of these innovative techniques. He was responsible for the notable discovery of the first New Zealand specimens of orange roughy in 1957 (which subsequently formed the basis of a multimillion-dollar fishery). Garrick collected some 721 specimens in 988 lots and deposited them at Te Papa.

Taxa named in his honour Garrick discovered the first known specimens of the northern river shark, a species that was eventually named after him, and which featured on an episode of the show River Monsters. Garrick's catshark Apristurus garricki was also named in his honour.

Worked examples

Example 1 — a first encounter with Jack Garrick

Start with the simplest possible case. Write down what Jack Garrick 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 Jack Garrick 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 Jack Garrick 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 Jack Garrick

In research: Jack Garrick 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 Jack Garrick 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: Jack Garrick is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2018 deaths, 20th-century New Zealand zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Jack Garrick 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.
