Stauroteuthis kengrahami

Stauroteuthis kengrahami 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 Stauroteuthis kengrahami rather than just read about it. In short: Stauroteuthis kengrahami is a species of small pelagic cirrate octopus. It is currently only known from off eastern Australia (Tasman Sea).

Key takeaways

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

Reference excerpt

Stauroteuthis kengrahami is a species of small pelagic cirrate octopus. It is currently only known from off eastern Australia (Tasman Sea). The species was named after Mr Ken Graham (fisheries research officer and Australian Museum Associate), who collected the only known specimen.

Description Stauroteuthis kengrahami, is generally similar to the other species in the genus. It is principally distinguished by having the cirri (long finger-like projections flanking the suckers) terminating at a much more distal sucker, but there are other differences in its V-shaped shell, and digestive system. It is only known from a female specimen, and the suckers of this specimen are much smaller than in S. gilchristi.

Distribution Stauroteuthis kengrahami is known from a single specimen collected off the coast at Batemans Bay, New South Wales, Australia, at a depth of 940–975 metres (3,080–3,200 ft).

Worked examples

Example 1 — a first encounter with Stauroteuthis kengrahami

Start with the simplest possible case. Write down what Stauroteuthis kengrahami 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 Stauroteuthis kengrahami 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 Stauroteuthis kengrahami 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 Stauroteuthis kengrahami

In research: Stauroteuthis kengrahami 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 Stauroteuthis kengrahami 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: Stauroteuthis kengrahami is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cephalopods described in 2023, Cephalopods of Australia, Octopuses, so understanding it makes those chapters shorter.
In everyday life: Look for Stauroteuthis kengrahami 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.
