Takasi Tokioka

Takasi Tokioka 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 Takasi Tokioka rather than just read about it. In short: Takasi Tokioka (時岡隆, Tokioka Takashi; 1913 – September 30, 2001) was a Japanese zoologist. He published over 200 scientific articles on marine animals such as chaetognaths, ctenophores, and tunicates.

Key takeaways

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

Reference excerpt

Takasi Tokioka (時岡隆, Tokioka Takashi; 1913 – September 30, 2001) was a Japanese zoologist. He published over 200 scientific articles on marine animals such as chaetognaths, ctenophores, and tunicates. He was Professor of Zoology at Kyoto University working at the Seto Marine Biological Laboratory in Shirahama, Japan. From 1975 to 1977, he was the Director of SMBL.

Eponymous species At least a dozen species are named in his honor, including these below.

Acartia tokiokai Mori, 1942 - Copepoda Atlanta tokiokai van der Spoel & Troost, 1972 - Heteropoda Bolivina tokiokai Uchio, 1962 - Foraminifera Eudistoma tokiokai Nishikawa, 1990 - Ascidiacea Euchromadora tokiokai Wieser, 1955 - Nematoda Krohnittella tokiokai Bieri, 1974 - Chaetognatha Ophiocentrus tokiokai Irimura, 1981 - Ophiuroidea Polycarpa tokiokai Monniot & Monniot, 1996 - Ascidiacea Styela tokiokai Nishikawa, 1991 - Ascidiacea

Worked examples

Example 1 — a first encounter with Takasi Tokioka

Start with the simplest possible case. Write down what Takasi Tokioka 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 Takasi Tokioka 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 Takasi Tokioka 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 Takasi Tokioka

In research: Takasi Tokioka 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 Takasi Tokioka 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: Takasi Tokioka is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2001 deaths, 20th-century Japanese zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Takasi Tokioka 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.
