Nicothoe tumulosa

Nicothoe tumulosa 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 Nicothoe tumulosa rather than just read about it. In short: Nicothoe tumulosa is a species of copepod parasitic on the gills of the glypheoid lobster Neoglyphea inopinata. It was described as a new species in 1976 by Roger F.

Key takeaways

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

Reference excerpt

Nicothoe tumulosa is a species of copepod parasitic on the gills of the glypheoid lobster Neoglyphea inopinata. It was described as a new species in 1976 by Roger F. Cressey. It can be differentiated from related species by the setal formula, and the trunk's covering of small bumps, which give the species its name.

Discovery A damaged decapod was collected in 1908 by the USFC Albatross in the Philippines. It was deposited in the United States National Museum, where it remained unidentified until Michèle de Saint Laurent examined it in 1975. Her colleague Jacques Forest recognised that it represented the first known extant species of the infraorder Glypheidea, which was thought to have been extinct since the Eocene, a conclusion endorsed by Fenner A. Chace, Jr. and Raymond B. Manning. Parasitic copepods were discovered on the gills of the Neoglyphea specimen, and were described in a 1976 paper by Roger F. Cressey. Five specimens were examined, all female, and all but one adults. The specific epithet tumulosa is from the Latin meaning "full of mounds", referring to the surface texture of the animal's back. N. tumulosa is the only species in the genus to parasitise animals other than clawed lobsters of the family Nephropidae (Homarus gammarus and species of Metanephrops).

Description The body of Nicothoe tumulosa is up to 1.24 millimetres (0.049 in) long, and up to 0.59 mm (0.023 in) wide. The preserved specimens are purple in colour. Most of the dorsal aspect is covered by three large plates; remaining areas of the trunk are covered with "small sclerotised bumps". N. tumulosa differs from other related species by the numbers of setae on its legs, and by the surface texture of the trunk. Females bear large egg sacs, similar to those in other copepod species, and each containing 50–60 eggs; the males are unknown.

Worked examples

Example 1 — a first encounter with Nicothoe tumulosa

Start with the simplest possible case. Write down what Nicothoe tumulosa 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 Nicothoe tumulosa 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 Nicothoe tumulosa 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 Nicothoe tumulosa

In research: Nicothoe tumulosa 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 Nicothoe tumulosa 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: Nicothoe tumulosa is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crustaceans described in 1976, Parasites of crustaceans, Siphonostomatoida, so understanding it makes those chapters shorter.
In everyday life: Look for Nicothoe tumulosa 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.
