Salinella

Salinella 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 Salinella rather than just read about it. In short: Salinella salve is a dubious species of a very simple animal which some have named as the sole member of the phylum Monoblastozoa. It was discovered in 1892 by Johannes Frenzel in the salt pans of Córdoba Province, Argentina and cultivated in a laboratory by him.

Key takeaways

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

Reference excerpt

Salinella salve is a dubious species of a very simple animal which some have named as the sole member of the phylum Monoblastozoa. It was discovered in 1892 by Johannes Frenzel in the salt pans of Córdoba Province, Argentina and cultivated in a laboratory by him. This animal has not been found since and its real existence is considered as doubtful. A project involving Michael Schrödl from the Zoological State Collection in Munich searched for Salinella in salt lakes across Argentina and Chile, but failed to find any specimens.

Discovery Salinella was discovered in soil samples from salt pans around Río Cuarto, Córdoba Province, Argentina, although the exact type locality was never specified.

Description According to Frenzel's description, S. salve is more organized than Protozoa, but still very primitive for a multicellular organism. They are characterised by their distinct anterior/posterior parts and being densely ciliated, especially around the "mouth" and "anus". They have only one layer of cells, and reproduce asexually by transverse fission of their bodies. Although sexual reproduction was suspected, Frenzel did not observe it.

Worked examples

Example 1 — a first encounter with Salinella

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

In research: Salinella 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 Salinella 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: Salinella is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic fauna of Argentina, Enigmatic animal taxa, Monotypic animal genera, so understanding it makes those chapters shorter.
In everyday life: Look for Salinella 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.

Frequently asked questions

What is Salinella in simple terms?

Why does Salinella matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Salinella?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
