Smalleye whip ray

Smalleye whip ray 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 Smalleye whip ray rather than just read about it. In short: The smalleye whip ray (Himantura microphthalma) is an obscure species of stingray in the family Dasyatidae. It is known only from a single specimen collected off Taiwan and assigned to the genus Dasyatis by J.T.F.

Key takeaways

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

Reference excerpt

The smalleye whip ray (Himantura microphthalma) is an obscure species of stingray in the family Dasyatidae. It is known only from a single specimen collected off Taiwan and assigned to the genus Dasyatis by J.T.F. Chen in 1948. In 1982, Leonard Compagno and Tyson Roberts moved it to the genus Himantura based on its apparent lack of a tail fold. In 2006, B. Mabel Manjaji-Matsumoto and Peter Last determined that the type specimen had been lost since Chen's description and that no further specimens have emerged since. Therefore, they considered this species to be a nomen dubium, perhaps conspecific with Dasyatis acutirostra.

Worked examples

Example 1 — a first encounter with Smalleye whip ray

Start with the simplest possible case. Write down what Smalleye whip ray 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 Smalleye whip ray 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 Smalleye whip ray 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 Smalleye whip ray

In research: Smalleye whip ray 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 Smalleye whip ray 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: Smalleye whip ray is common in secondary-school and first-year university syllabi. It links to neighbouring topics Himantura, Nomina dubia, Species known from a single specimen, so understanding it makes those chapters shorter.
In everyday life: Look for Smalleye whip ray 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.
