Halicampus mataafae

Halicampus mataafae 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 Halicampus mataafae rather than just read about it. In short: The Samoan pipefish, or brown pipefish (Halicampus mataafae), is a species of marine fish of the family Syngnathidae. It is found in the Indo-Pacific, from the Red Sea, to Sodwana Bay, to Taiwan, the Marshall Islands, and Samoa, where it inhabits tidepools and coral and rocky reefs to depths of 15 metres (49 ft).

Key takeaways

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

Reference excerpt

The Samoan pipefish, or brown pipefish (Halicampus mataafae), is a species of marine fish of the family Syngnathidae. It is found in the Indo-Pacific, from the Red Sea, to Sodwana Bay, to Taiwan, the Marshall Islands, and Samoa, where it inhabits tidepools and coral and rocky reefs to depths of 15 metres (49 ft). It is a solitary species with cryptic habits and is rarely observed. It is likely to feed on small crustaceans, and can grow to lengths of 14 centimetres (5.5 in). This species is ovoviviparous, with males carrying the fertilised eggs in a brood pouch, the folds of which fall well short of the centre of the egg-filled pouch, eventually giving birth to live young.

Etymology The specific name honours Mataafa, a former king of Samoa. It is a listed marine species under the Australian Environment Protection and Biodiversity Conservation Act 1999.

Identification H. mataafae can be identified by its reddish-brown colouring and small pale spots on its trunk and tail.

Worked examples

Example 1 — a first encounter with Halicampus mataafae

Start with the simplest possible case. Write down what Halicampus mataafae 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 Halicampus mataafae 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 Halicampus mataafae 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 Halicampus mataafae

In research: Halicampus mataafae 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 Halicampus mataafae 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: Halicampus mataafae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fish described in 1906, Halicampus, IUCN Red List least concern species, so understanding it makes those chapters shorter.
In everyday life: Look for Halicampus mataafae 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.
