Pseudophilautus leucorhinus

Pseudophilautus leucorhinus 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 Pseudophilautus leucorhinus rather than just read about it. In short: Pseudophilautus leucorhinus, also known as white-nosed shrub frog, pointed-nosed shrub frog, whitenose bubble-nest frog, and Marten's bush frog, was a species of frog in the family Rhacophoridae. It was endemic to Sri Lanka.

Reference excerpt

Pseudophilautus leucorhinus, also known as white-nosed shrub frog, pointed-nosed shrub frog, whitenose bubble-nest frog, and Marten's bush frog, was a species of frog in the family Rhacophoridae. It was endemic to Sri Lanka. It is only known from the holotype that was collected some time before 1856 from the indefinite type locality "Ceylon". Pseudophilautus wynaadensis from southwestern India has been considered conspecific with this species, but these species are now considered distinct.

Description The holotype measures 20 mm (0.8 in) in snout–vent length. The body is elongate. The head is dorsally flat. The tympanum is not visible and the supratympanic fold is weakly defined. The toes are partially webbed. The alcohol-preserved specimen is dorsally pale brownish-yellow. There is a darker brown interorbital bar. The upper lip is pale pale brownish-yellow. The flanks and sides of the head are dark brown, with the lower flank and inguinal zone being pale brownish-yellow. The limbs have dark-brown crossbars. The lower parts of the body are pale brown-yellow.

Habitat and conservation The former habitat of this species is unknown. It probably had direct development (i.e., there is no free-living larval stage). The factors leading to its extinction are unknown but probably involved habitat loss.

Worked examples

Example 1 — a first encounter with Pseudophilautus leucorhinus

Start with the simplest possible case. Write down what Pseudophilautus leucorhinus 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 Pseudophilautus leucorhinus 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 Pseudophilautus leucorhinus 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 Pseudophilautus leucorhinus

In research: Pseudophilautus leucorhinus 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 Pseudophilautus leucorhinus 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: Pseudophilautus leucorhinus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibian extinctions since 1500, Amphibians described in 1856, Endemic amphibians of Sri Lanka, so understanding it makes those chapters shorter.
In everyday life: Look for Pseudophilautus leucorhinus 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.
