Reference excerpt

Poisonous amphibians are amphibians that produce toxins to defend themselves from predators.

Amphibians Most toxic amphibians are poisonous to touch or eat. These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants. Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, and two species of frogs with venom-tipped bone spurs on their skulls, amphibians are not known to actively inject venom.

Toxic Frogs and Toads An example of poison ingestion derives from the poison dart frog. They get a deadly chemical called lipophilic alkaloid from consuming a poisonous food in the rainforest. They are immune to the poison and they secrete it through their skin as a defense mechanism against predators. This poison is so efficient, the native people of the South American Amazon rainforest use the frogs' toxins on their weapons to kill their prey, giving the frogs their nickname the "poison dart frog".

Toxic Salamanders

Recreational ingestion of toxins Some people use the bufotoxins of some species of toxic toads as a drug to get high, but this can become very dangerous. Usually due to the toads' size and toxicity, the poisons would not be deadly to a fully grown, healthy adult. But if too much of the toxin is absorbed, or if the person is young or ill, then the poisons can become a serious threat. It also depends on species: some amphibians do have toxins strong enough to kill even a healthy mature person within just a few minutes, while other species may not have toxins potent enough to have any effect. Licking toads is not biologically practical. For these tryptamines to be orally activated, the human monoamine oxidase system must be inhibited. Therefore, licking a poisonous amphibian will not guarantee a sufficient dose.

Worked examples

Example 1 — a first encounter with Poisonous amphibian

Start with the simplest possible case. Write down what Poisonous amphibian claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Poisonous amphibian 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 Poisonous amphibian 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 Poisonous amphibian

In research: Poisonous amphibian appears in science 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 Poisonous amphibian 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: Poisonous amphibian is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibian toxins, Amphibians, Poisonous animals, so understanding it makes those chapters shorter.
In everyday life: Look for Poisonous amphibian 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.
