Lepotrema justinei

Lepotrema justinei 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 Lepotrema justinei rather than just read about it. In short: Lepotrema justinei is a species of lepocreadiid digenean parasitic in the intestine of marine fish. It was described in 2018.

Key takeaways

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

Reference excerpt

Lepotrema justinei is a species of lepocreadiid digenean parasitic in the intestine of marine fish. It was described in 2018. This species was not characterised by molecular means but was distinguished from other species of the genus Lepotrema by morphological characteristics. It is the only species with more or less symmetrical testes, and, probably as a result, it tends to be broader than the other species.

Etymology According to Bray, Cutmore & Cribb, the species was named justinei "after Professor Jean-Lou Justine of the Muséum National d’Histoire Naturelle, Paris, France, in recognition of his massive contributions to marine fish parasitology".

Hosts and localities

The masked triggerfish, Sufflamen fraenatum, (Tetraodontiformes: Balistidae) is the type-host of Lepotrema justinei. The type-locality is the Interior Lagoon near Récif Toombo, off Nouméa, New Caledonia.

Worked examples

Example 1 — a first encounter with Lepotrema justinei

Start with the simplest possible case. Write down what Lepotrema justinei 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 Lepotrema justinei 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 Lepotrema justinei 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 Lepotrema justinei

In research: Lepotrema justinei 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 Lepotrema justinei 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: Lepotrema justinei is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animals described in 2018, Flatworms of New Caledonia, Parasites of fish, so understanding it makes those chapters shorter.
In everyday life: Look for Lepotrema justinei 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.
