List of endangered amphibians

List of endangered amphibians 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 List of endangered amphibians rather than just read about it. In short: As of December 2025, the International Union for Conservation of Nature (IUCN) lists 1291 endangered amphibian species. Of all evaluated amphibian species, 16% are listed as endangered.

Key takeaways

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

Reference excerpt

As of December 2025, the International Union for Conservation of Nature (IUCN) lists 1291 endangered amphibian species. Of all evaluated amphibian species, 16% are listed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered amphibians are listed separately. There are 2116 amphibian species which are endangered or critically endangered. Additionally 896 amphibian species (11.1% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed". This is a complete list of endangered amphibian species evaluated by the IUCN, last substantially updated February 2022.

Worked examples

Example 1 — a first encounter with List of endangered amphibians

Start with the simplest possible case. Write down what List of endangered amphibians 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 List of endangered amphibians 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 List of endangered amphibians 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 List of endangered amphibians

In research: List of endangered amphibians 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 List of endangered amphibians 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: List of endangered amphibians is common in secondary-school and first-year university syllabi. It links to neighbouring topics IUCN Red List endangered species, Lists of amphibians, Lists of animals by conservation status, so understanding it makes those chapters shorter.
In everyday life: Look for List of endangered amphibians 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.
