Insuetophrynus

Insuetophrynus 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 Insuetophrynus rather than just read about it. In short: Insuetophrynus is a monotypic genus of frogs in the family Rhinodermatidae. The sole species is Insuetophrynus acarpicus, also known as Barrio's frog.

Key takeaways

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

Reference excerpt

Insuetophrynus is a monotypic genus of frogs in the family Rhinodermatidae. The sole species is Insuetophrynus acarpicus, also known as Barrio's frog. It is endemic to Chile and only known from few localities on the Valdivian Coast Range between Chanchán in the Los Ríos Region in the south and Queule (southernmost Araucanía Region) and Colequal Alto in the north; the fourth locality is Mehuín, which is the type locality. The altitudinal range is 50–486 m (164–1,594 ft) asl.

Description Adult males measure 41–56 mm (1.6–2.2 in) and females 35–53 mm (1.4–2.1 in) in snout–vent length. The body is sturdy with muscular arms and legs (these frogs are powerful jumpers). The toes are partially webbed and thinner than the fingers which are short, thick, and unwebbed. The head is wider than long, with a broad, rounded snout. The eyes are large, and tympanum is visible but not large. The back is reddish brown with some whitish granulations. The hind legs have transverse, darker bands. The throat is pinkish yellow, and the stomach is pale. Skin is dorsally quite granular or warty. Also ventral region is also very granular, apart from the throat that is fairly smooth. The tadpoles can reach 61.00 mm in total length by stage 43. The skin of the dorsum is green-brown in color with some mottling. The tail and fins have light brown spots made of melanophores and guanophores. The skin of the ventrum is clear, with the viscera visible to the naked eye.

Habitat and conservation Insuetophrynus acarpicus inhabits coastal streams in temperate forest. They spend a great deal of time in the water even though they do not swim well. Adults hide under stones during the day, emerging at night to feed along the stream margins. Tadpoles can be found under stones in muddy areas with slow current. The species has a small area of distribution (its known range extends only 33 km along the coast) and its habitat is threatened by clear cutting and afforestation.

Worked examples

Example 1 — a first encounter with Insuetophrynus

Start with the simplest possible case. Write down what Insuetophrynus 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 Insuetophrynus 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 Insuetophrynus 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 Insuetophrynus

In research: Insuetophrynus 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 Insuetophrynus 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: Insuetophrynus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians, EDGE species, Endemic amphibians of Chile, so understanding it makes those chapters shorter.
In everyday life: Look for Insuetophrynus 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.
