Tristramella sacra

Tristramella sacra 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 Tristramella sacra rather than just read about it. In short: Tristramella sacra, the long jaw tristramella, is a species of cichlid fish that was endemic to the Sea of Galilee in Israel. It has not been recorded since 1990, despite searches both of the lake and in local markets, and it is regarded as extinct by the IUCN.

Key takeaways

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

Reference excerpt

Tristramella sacra, the long jaw tristramella, is a species of cichlid fish that was endemic to the Sea of Galilee in Israel. It has not been recorded since 1990, despite searches both of the lake and in local markets, and it is regarded as extinct by the IUCN. This species could reach a total length of up to 28 cm (11 in). The long jaw tristamella has not been seen since 1990 and declared extinct by the IUCN in 2014. T. sacra's spawning ground was the marshy northern margin of the lake. This dried out in 1991 and again in the mid-1990s, destroying this species' breeding habitat and therefore possibly causing its disappearance. Water levels in the Sea of Galilee may have been under stress since Israel's National Water Carrier was built in 1964, and this stress may have been increased since the Israel–Jordan peace treaty of 1994 committed Israel to supply 50 million cubic meters of water per year from the lake to Jordan.

Worked examples

Example 1 — a first encounter with Tristramella sacra

Start with the simplest possible case. Write down what Tristramella sacra 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 Tristramella sacra 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 Tristramella sacra 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 Tristramella sacra

In research: Tristramella sacra 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 Tristramella sacra 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: Tristramella sacra is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cichlid fish of Asia, Endemic fauna of Israel, Fish described in 1865, so understanding it makes those chapters shorter.
In everyday life: Look for Tristramella sacra 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.
