Koh Tao Island caecilian

Koh Tao Island caecilian 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 Koh Tao Island caecilian rather than just read about it. In short: The Koh Tao Island caecilian (Ichthyophis kohtaoensis) is a species of amphibian in the family Ichthyophiidae found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. Also known as the Ichthyophis bannanicus, the Banna caecilian, it is also found in southern China.

Key takeaways

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

Reference excerpt

The Koh Tao Island caecilian (Ichthyophis kohtaoensis) is a species of amphibian in the family Ichthyophiidae found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. Also known as the Ichthyophis bannanicus, the Banna caecilian, it is also found in southern China. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, intermittent rivers, swamps, freshwater marshes, intermittent freshwater marshes, plantations, rural gardens, urban areas, heavily degraded former forests, irrigated land, and seasonally flooded agricultural land. It is threatened by habitat loss.

The scientific name refers to Ko Tao Island in the Gulf of Siam, where the type specimen was collected.

Genetics The mitotic karyotypes of both the female and male Koh Tao caecilians have 21 pairs of chromosomes, although in a study performed by Nussbaum and Treisman, it was found that there was an inconsistent report of chromosomes. While they all may have the 21 chromosome pairs, there was a study that found they have 18 metacentric, 4 submetacentric, and 20 telocentric chromosomes while another study had found 16 metacentric, 6 submetacentric, and 20 telocentric chromosomes in the caecilians. The conclusion that Ichthyophis genus is a karyologically conserved taxa when it comes to looking at the chromosome numbers.

Worked examples

Example 1 — a first encounter with Koh Tao Island caecilian

Start with the simplest possible case. Write down what Koh Tao Island caecilian 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 Koh Tao Island caecilian 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 Koh Tao Island caecilian 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 Koh Tao Island caecilian

In research: Koh Tao Island caecilian 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 Koh Tao Island caecilian 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: Koh Tao Island caecilian is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1960, Amphibians of Cambodia, Amphibians of Laos, so understanding it makes those chapters shorter.
In everyday life: Look for Koh Tao Island caecilian 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.
