Grimpoteuthis discoveryi

Grimpoteuthis discoveryi 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 Grimpoteuthis discoveryi rather than just read about it. In short: Grimpoteuthis discoveryi is a small species of octopus known from more than 50 specimens. It was described in 2003, but specimens have been found as early as 1910.

Key takeaways

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

Reference excerpt

Grimpoteuthis discoveryi is a small species of octopus known from more than 50 specimens. It was described in 2003, but specimens have been found as early as 1910. The type species was found at 49°35'N, 14°01'W, southwest of Ireland.

Description At maximum, Grimpoteuthis discoveryi's mantle is 58 millimeters in length, and its body in total reaches 370 millimeters. Its arms are long. G. discoveryi, like other cirrates, has a web covering its arms to some degree; this species' web reaches 2/3 of its arm length. The suckers on its arms number between 56 and 61. The suckers of female specimens are smaller than the suckers of males, and are also differently shaped. The range in mantle size are larger in females (32-58mm) than males (25-52mm). The posterior salivary glands and radula are both absent in this species, however, its anterior salivary glands are present. The species' body is white, and its eyes are dark grey or black when preserved. It's possible that G. discoveryi is actually two separate species.

Habitat and population This species has been found in the bathyal zone (also called the midnight zone), specifically from 2,600 to 4,870 meters below the surface. It lives in the Porcupine Seabight of the northeast Atlantic Ocean. G. discoveryi may be a demersal species, occupying both rocky and soft seafloor. While its population is unknown, the species is classified as Least Concern because it lives at such depths, where human activity is unlikely to affect it.

Worked examples

Example 1 — a first encounter with Grimpoteuthis discoveryi

Start with the simplest possible case. Write down what Grimpoteuthis discoveryi 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 Grimpoteuthis discoveryi 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 Grimpoteuthis discoveryi 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 Grimpoteuthis discoveryi

In research: Grimpoteuthis discoveryi 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 Grimpoteuthis discoveryi 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: Grimpoteuthis discoveryi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cephalopods described in 2003, IUCN Red List least concern species, Molluscs of Europe, so understanding it makes those chapters shorter.
In everyday life: Look for Grimpoteuthis discoveryi 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.
