Hydrophis sibauensis

Hydrophis sibauensis 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 Hydrophis sibauensis rather than just read about it. In short: Hydrophis sibauensis, also known as the Kalimantan sea snake, is a species of venomous sea snake in the family Elapidae that is native to Indonesia, and endemic to Borneo. The specific epithet sibauensis refers to the Sibau River.

Key takeaways

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

Reference excerpt

Hydrophis sibauensis, also known as the Kalimantan sea snake, is a species of venomous sea snake in the family Elapidae that is native to Indonesia, and endemic to Borneo. The specific epithet sibauensis refers to the Sibau River. It is notable for being one of only two known species of sea snake that are only found in freshwater, the other species being Hydrophis semperi.

Behaviour The species is viviparous.

Distribution and habitat The range of the snake is limited to the Sibau River, a tributary of the Kapuas River, in West Kalimantan, Borneo, in fresh water some 1,000 km upriver from the sea. The type locality is Putussibau.

Worked examples

Example 1 — a first encounter with Hydrophis sibauensis

Start with the simplest possible case. Write down what Hydrophis sibauensis 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 Hydrophis sibauensis 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 Hydrophis sibauensis 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 Hydrophis sibauensis

In research: Hydrophis sibauensis 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 Hydrophis sibauensis 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: Hydrophis sibauensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Elapidae stubs, Endemic fauna of Borneo, Hydrophis, so understanding it makes those chapters shorter.
In everyday life: Look for Hydrophis sibauensis 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.
