Oxychilus cellarius

Oxychilus cellarius 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 Oxychilus cellarius rather than just read about it. In short: Oxychilus cellarius, common name cellar glass-snail, is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oxychilidae, the glass snails. Description The shell has 5.5-6 regularly increasing whorls.

Key takeaways

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

Reference excerpt

Oxychilus cellarius, common name cellar glass-snail, is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oxychilidae, the glass snails.

Description The shell has 5.5-6 regularly increasing whorls. The last whorl is not inflated and narrower than in Oxychilus draparnaudi. The shell is nearly smooth and shiny and only very faintly striated. The umbilicus is moderately deep and open. The width of the shell is 7–11 mm, 0.28–0.43 in (14 mm, 0.55 in maximum). The height of the shell is 4.5–6 mm, 0.18–0.24 in. The animal is usually pale bluish grey. Genitalia: Penis cylindrical without constrictions (in contrast to Oxychilus draparnaudi), rows of papillae of penis continuous without interruption (interrupted at the constriction in Oxychilus draparnaudi).

Distribution This species occurs in countries and islands including:

Czech Republic Poland Slovakia Great Britain Ireland New Zealand (e.g. Dunedin).

Habitat Oxychilus cellarius occurs in a number of habitats, like in forests and in habitats modified by humans, such as gardens and green houses.

Worked examples

Example 1 — a first encounter with Oxychilus cellarius

Start with the simplest possible case. Write down what Oxychilus cellarius 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 Oxychilus cellarius 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 Oxychilus cellarius 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 Oxychilus cellarius

In research: Oxychilus cellarius 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 Oxychilus cellarius 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: Oxychilus cellarius is common in secondary-school and first-year university syllabi. It links to neighbouring topics Gastrodontoidea stubs, Gastropods described in 1774, IUCN Red List least concern species, so understanding it makes those chapters shorter.
In everyday life: Look for Oxychilus cellarius 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.
