Phrynomedusa fimbriata

Phrynomedusa fimbriata 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 Phrynomedusa fimbriata rather than just read about it. In short: Phrynomedusa fimbriata, the spiny-knee leaf frog, is an extinct species of tree frog. It was endemic to Brazil, where the only known specimen was discovered near Paranapiacaba in the state of São Paulo.

Key takeaways

Phrynomedusa fimbriata belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Phrynomedusa fimbriata to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Phrynomedusa fimbriata, the spiny-knee leaf frog, is an extinct species of tree frog. It was endemic to Brazil, where the only known specimen was discovered near Paranapiacaba in the state of São Paulo. The type locality was given as Alto da Serra. While the species might still exist, having only been found once in the 1898, no trace of any individuals have been discovered in successive expeditions.

Description This species is only known from the holotype, an adult female measuring 46 mm (1.8 in) in snout–vent length. The specimen was collected in 1898 and is now in bad condition with completely faded colors. At the time of species description, the holotype was dorsally pale blue and ventrally reddish yellow. Phrynomedusa fimbriata is a relatively robust frog for its genus. The snout is acuminate in dorsal view and markedly oblique in lateral view. The tympanum is visible, rounded, and has a visible tympanic annulus. The limbs are slender. The fingers and toes are slender and have reduced webbing and rounded adhesive discs.

Habitat and conservation The natural history of this species is unknown. Possibly it was a high-altitude stream-breeder. The reason for its disappearance are unknown. The area hosts some protected areas, namely the Serra do Mar State Park and Reserva Biológica do Alto da Serra de Paranapiacaba.

Worked examples

Example 1 — a first encounter with Phrynomedusa fimbriata

Start with the simplest possible case. Write down what Phrynomedusa fimbriata 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 Phrynomedusa fimbriata 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 Phrynomedusa fimbriata 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 Phrynomedusa fimbriata

In research: Phrynomedusa fimbriata 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 Phrynomedusa fimbriata 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: Phrynomedusa fimbriata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibian extinctions since 1500, Amphibians described in 1923, Endemic frogs of Brazil, so understanding it makes those chapters shorter.
In everyday life: Look for Phrynomedusa fimbriata 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.
