Holcomycteronus profundissimus

Holcomycteronus profundissimus 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 Holcomycteronus profundissimus rather than just read about it. In short: Holcomycteronus profundissimus, also known by its synonym Grimaldichthys profundissimus, (Danish: Grimaldis slangekvabbe; Finnish: Grimaldikala; Italian: Pesce di Grimaldi) is a species of deep-sea fish in the cusk-eel family. The fish has an elongated body of a uniform sallow yellowish color.

Key takeaways

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

Reference excerpt

Holcomycteronus profundissimus, also known by its synonym Grimaldichthys profundissimus, (Danish: Grimaldis slangekvabbe; Finnish: Grimaldikala; Italian: Pesce di Grimaldi) is a species of deep-sea fish in the cusk-eel family. The fish has an elongated body of a uniform sallow yellowish color. It is about 22 cm (9 in) in length and has rudimentary eyes. Very little is known about its habitat, ecology and biology.

History The first specimen was found in Atlantic waters in August 1901 at a depth of 6,035 m (19,800 ft) in the hadal zone southwest of the Cape Verde Islands. It was caught during an oceanographic cruise by Princess Alice of Monaco using a fish trap designed by her husband Prince Albert I. The genus to which this species belongs was initially named Grimaldichthys after the ruling family of Monaco. Other specimens of this fish were recorded later in the Pacific and the Eastern Indian oceans at depths between 5,180 and 7,160 m (16,990–23,490 ft). For many decades it was thought to be the fish living at the greatest depth in the world until the species Abyssobrotula galatheae—one specimen of which was found at a depth of over 8,000 m (26,000 ft)—was described in 1977.

Worked examples

Example 1 — a first encounter with Holcomycteronus profundissimus

Start with the simplest possible case. Write down what Holcomycteronus profundissimus 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 Holcomycteronus profundissimus 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 Holcomycteronus profundissimus 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 Holcomycteronus profundissimus

In research: Holcomycteronus profundissimus 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 Holcomycteronus profundissimus 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: Holcomycteronus profundissimus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Deep sea fish, Fish described in 1913, IUCN Red List least concern species, so understanding it makes those chapters shorter.
In everyday life: Look for Holcomycteronus profundissimus 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.
