Typhlocaris galilea

Typhlocaris galilea 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 Typhlocaris galilea rather than just read about it. In short: Typhlocaris galilea is a species of troglobitic shrimp in the genus Typhlocaris, and is endemic to one pool and spring that feeds it, at Tabgha in Israel. The species is critically endangered and a conservation programme to conserve the species has begun.

Key takeaways

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

Reference excerpt

Typhlocaris galilea is a species of troglobitic shrimp in the genus Typhlocaris, and is endemic to one pool and spring that feeds it, at Tabgha in Israel. The species is critically endangered and a conservation programme to conserve the species has begun.

Description The relict species was first described in 1909, by William Thomas Calman. The shrimp are semi-transparent and blind. Adult specimens are approximately 3 inches (7.6 cm) long. Their diet probably consists mainly of a small red tubificid worm, Isochaeta israelis.

Distribution The shrimp is endemic to one chamber of a Roman cistern, Ein-Nur octagonal pool (the private property of a monastery, at 32.8736°N 35.5493°E / 32.8736; 35.5493), and a warm (27 °C or 81 °F), sulphuric, saline subterranean spring that feeds it, at Tabgha, on the north shore of the Sea of Galilee in Israel.

Conservation The species is now critically endangered, as the extraction of ground water has allowed foreign water into the pool, changing its composition and temperature. It is legally protected (Section 5, paragraphs D and E, of the Fisheries Rules of 1937 as amended). In 2013, the Israel Nature and Parks Authority approached the Jerusalem Biblical Zoo to develop a captive breeding programme for the species, with a view to later reintroduction.

Worked examples

Example 1 — a first encounter with Typhlocaris galilea

Start with the simplest possible case. Write down what Typhlocaris galilea 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 Typhlocaris galilea 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 Typhlocaris galilea 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 Typhlocaris galilea

In research: Typhlocaris galilea 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 Typhlocaris galilea 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: Typhlocaris galilea is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cave shrimp, Critically endangered animals, Crustaceans described in 1909, so understanding it makes those chapters shorter.
In everyday life: Look for Typhlocaris galilea 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.
