Ichthyophis singaporensis

Ichthyophis singaporensis 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 Ichthyophis singaporensis rather than just read about it. In short: Ichthyophis singaporensis, the Singapore caecilian, is a species of amphibian in the family Ichthyophiidae endemic to Singapore. Its natural habitats are subtropical or tropical moist lowland forests, rivers, intermittent rivers and former plantations.

Key takeaways

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

Reference excerpt

Ichthyophis singaporensis, the Singapore caecilian, is a species of amphibian in the family Ichthyophiidae endemic to Singapore. Its natural habitats are subtropical or tropical moist lowland forests, rivers, intermittent rivers and former plantations. Currently, it is now restricted to the Central Catchment Nature Reserve. It has not been sighted for almost fifty years, and is possibly extinct. It might have existed in south Peninsula Malaysia in historic times. William Montgomerie was the island's first surgeon as well as Raffles's physician. The specimen was first identified as a species already known to science and sat amongst the unimaginable multitude of other specimens at what is today the Natural History Museum in London. Over a century after it was first collected, Edward Harrison Taylor studied this and other specimens of caecilians, which are legless amphibians that resemble snakes. Taylor concluded that this was a new species and named it Ichthyophis singaporensis from whence the specimen originated. It is commonly known as the Singapore caecilian. Remarkably, despite being Singapore's rarest amphibian, being known only from the type-specimen, I. singaporensis was also the first amphibian recorded from Singapore. Ichthyophis singaporensis was first described as ' I. glutinosus Var? ' by Cantor who received the specimen from Montgomerie in 1843 when it was dug up from his garden. Hanitsch incorrectly listed the collection date as 1863. Cantor found the specimen to differ from I. paucisulcus, but did not find conclusive data to designate it as a new species. Ichthyophis singaporensis was later described as a new species by Taylor. He included three specimens collected from Peninsular Malaysia as part of I. singaporensis. The specimens are from " Selangor ", Batu Gajah, and Kuala Kangsi. As of today, I. singaporensis is only known from these four specimens. No live photographs exist of I. singaporensis, but Taylor provides a radiographic image of the specimen. It is only known from a type-specimen predating 1847.

Worked examples

Example 1 — a first encounter with Ichthyophis singaporensis

Start with the simplest possible case. Write down what Ichthyophis singaporensis 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 Ichthyophis singaporensis 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 Ichthyophis singaporensis 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 Ichthyophis singaporensis

In research: Ichthyophis singaporensis 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 Ichthyophis singaporensis 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: Ichthyophis singaporensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1960, Amphibians of Singapore, Caecilian stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Ichthyophis singaporensis 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.
