Reference excerpt

Ciliophrys azurina is a species of heliozoan protists, amoeboid eukaryotes with stiff axopodia radiating from their cells.

Morphology Ciliophrys azurina is a heliozoan, a unicellular protist with tapering arms called axopodia sustained by axonemes. Cells of C. azurina have a large, prominent cell nucleus containing a central nucleolus surrounded by peripheral clumps of heterochromatin. The cell body measures 15 μm in diameter, with radiating arms that contain extrusomes. Each cell has a single flagellum that appears at the front of swimming cells or, in non-swimming cells (i.e. during feeding), appears tightly curled, typically in a double "8" shape. Both its large size and the length and shape of its flagellum make it similar to Actinophrys, specifically A. pontica.

Ecology Ciliophrys azurina is a heterotrophic flagellate exclusively found in tropical climates, in both marine and terrestrial habitats. It was isolated from Darwin, Northern Territory, Australia, where it was observed consuming diatoms. It is present in intertidal sediments and surface waters of Darwin. It has also been observed in Ascension Island.

Systematics Ciliophrys azurina is a species previously assigned to the genus Ciliophrys of the Pedinellales, a heliozoan order assigned to Dictyochophyceae, a class of ochrophytes. It was created in 2001 by biologist David J. Patterson to describe cells collected in 1994 from East Point and Lee Point, Darwin, Northern Territory, Australia. In its initial publication, C. azurina (then Ciliophrys azurina) was considered an "evolutionary link" between the Pedinellales and the order Actinophryida, on the basis of presenting traits previously thought as exclusive to each order. The species differs from other Ciliophrys by the presence of tapering axopodia that are too broad at the base to be sustained solely by a triad of microtubules, a characteristic of Pedinellales. The genus Ciliophrys is now classified in the dictyochophyte order Rhizochromulinales.

Worked examples

Example 1 — a first encounter with Ciliophrys azurina

Start with the simplest possible case. Write down what Ciliophrys azurina 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 Ciliophrys azurina 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 Ciliophrys azurina 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 Ciliophrys azurina

In research: Ciliophrys azurina 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 Ciliophrys azurina 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: Ciliophrys azurina is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ochrophyta, Ochrophyte genera, Taxa described in 2013, so understanding it makes those chapters shorter.
In everyday life: Look for Ciliophrys azurina 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.
