Tatria duodecacantha

Tatria duodecacantha is a science 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 Tatria duodecacantha rather than just read about it. In short: Tatria duodecacantha is a species of tapeworm in the family Amabiliidae. It infects the pied-billed grebe (Podilymbus podiceps podiceps).

Key takeaways

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

Reference excerpt

Tatria duodecacantha is a species of tapeworm in the family Amabiliidae. It infects the pied-billed grebe (Podilymbus podiceps podiceps). Tatria duodecacantha was discovered in 1939 in Iowa but has also been reported from pied-billed grebes in Oklahoma. Morphologically, Tatria duodecacantha differs from other Tatria species by the number and shape of the rostellar hooks. It typically has 12 rostellar hooks but the number can vary. Around one in five worms has a different number of hooks, ranging from at least 10-13 hooks.

Worked examples

Example 1 — a first encounter with Tatria duodecacantha

Start with the simplest possible case. Write down what Tatria duodecacantha 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 Tatria duodecacantha 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 Tatria duodecacantha 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 Tatria duodecacantha

In research: Tatria duodecacantha 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 Tatria duodecacantha 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: Tatria duodecacantha is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animals described in 1939, Cestoda stubs, Eucestoda, so understanding it makes those chapters shorter.
In everyday life: Look for Tatria duodecacantha 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.
