Reference excerpt

Scorpaena sumptuosa, the western red scorpionfish, western red rockcod, western red scorpioncod or western scorpionfish, is a venomous species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. It is found in Western Australia.

Taxonomy Scorpaena sumptuosa was first formally described in 1875 by the French naturalist François-Louis Laporte, comte de Castelnau with the type locality given as Fremantle in Western Australia. The specific name sumptuosa means "magificent" in Latin, Castelnau did not explain this but it may refer to the deep red colour of this species.

Description Scorpaena sumptuosa is distinguished from most other species of Scorpaena found in the Indo-Pacific by its maxillary ridge, very deep occipital pit, thickened skin with many pores near the lateral line and covering the spine on the operculum and the presence of two pairs of slender tentacles on the front off the lower jaw. There are 16 fin rays in the pectoral fin. It is closely related to the ghost scorpionfish (Scorpaena gasta) but is larger, has fewer tentacles on the flanks and more variable in colour. This species reaches a maximum total length of 40 cm (16 in). This is a deep-bodied species with an obvious hump on the shoulder. Tentacles cover the body with the effect of disrupting the outline of the body to provide camouflage and the eyes are high on the head. It is a mottled red to brown colour marked with two wide vertical bands on the body, these extend onto the fins.

Distribution and habitat Scorpaena sumptuosa is endemic to Western Australia where it occurs from the Shark Bay in the north to Albany in the south. It is found on coastal reefs in depths down to 60 m (200 ft).

Biology Scorpaena sumptuosa is an ambush predator, they lie motionless for lengthy periods, among corals, algae and benthic invertebrates and use their prehensile mouths to suck in prey which comes in range. They are protected by venom bearing spines which can deliver a painful sting.

Worked examples

Example 1 — a first encounter with Scorpaena sumptuosa

Start with the simplest possible case. Write down what Scorpaena sumptuosa 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 Scorpaena sumptuosa 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 Scorpaena sumptuosa 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 Scorpaena sumptuosa

In research: Scorpaena sumptuosa 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 Scorpaena sumptuosa 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: Scorpaena sumptuosa is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fish described in 1875, Marine fish of Western Australia, Scorpaena, so understanding it makes those chapters shorter.
In everyday life: Look for Scorpaena sumptuosa 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.
