Veiled anglemouth

Veiled anglemouth 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 Veiled anglemouth rather than just read about it. In short: The veiled anglemouth (Cyclothone microdon) is a bristlemouth of the family Gonostomatidae, abundant in all the world's oceans at depths of 300–2,500 meters (980–8,200 feet). Its length is 10–15 cm (4–6 in) though the largest known specimen is 7.6 cm (3.0 in).

Key takeaways

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

Reference excerpt

The veiled anglemouth (Cyclothone microdon) is a bristlemouth of the family Gonostomatidae, abundant in all the world's oceans at depths of 300–2,500 meters (980–8,200 feet). Its length is 10–15 cm (4–6 in) though the largest known specimen is 7.6 cm (3.0 in). It gets its name from its circular mouth, filled with small teeth: the name "cyclothone" means in a circle or around and "microdon" means small teeth. The International Union for Conservation of Nature (IUCN) has assessed the veiled anglemouth is of Least Concern due to its abundance in most oceans and the little effect human impact has on its population growth. Some of the veiled anglemouth's physical features include a brown to black body with a radiating, or expansive, bioluminescent pigment over its head and fins.

Worked examples

Example 1 — a first encounter with Veiled anglemouth

Start with the simplest possible case. Write down what Veiled anglemouth 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 Veiled anglemouth 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 Veiled anglemouth 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 Veiled anglemouth

In research: Veiled anglemouth 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 Veiled anglemouth 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: Veiled anglemouth is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actinopterygii stubs, Deep sea fish, Fish described in 1878, so understanding it makes those chapters shorter.
In everyday life: Look for Veiled anglemouth 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.
