Goniobranchus roboi

Goniobranchus roboi is a earth 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 Goniobranchus roboi rather than just read about it. In short: Goniobranchus roboi, common name the tooth-edged chromodoris, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae. This species was transferred from Chromodoris to Goniobranchus in 2012.

Key takeaways

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

Reference excerpt

Goniobranchus roboi, common name the tooth-edged chromodoris, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae. This species was transferred from Chromodoris to Goniobranchus in 2012.

Distribution This marine species occurs in the tropical Indo-West Pacific. It was described from Okinawa, Japan. It has been reported from Queensland, New South Wales, Sulawesi, Réunion and South Africa. Similar animals from Western Australia have a different pattern on the mantle and are intermediate between G. roboi and Goniobranchus aurigerus. There are several similar species which are not yet studied or named.

Description Goniobranchus roboi is a chromodorid nudibranch with a yellow mantle densely areolated with small white and larger lilac spots. The edge of the mantle is blue grading to white with dark purple stripes at right angles to the margin. The rhinophores and gills are white at the base grading into dark purple. The body length varies between 40 mm and 60 mm.

Worked examples

Example 1 — a first encounter with Goniobranchus roboi

Start with the simplest possible case. Write down what Goniobranchus roboi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Goniobranchus roboi 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 Goniobranchus roboi 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 Goniobranchus roboi

In research: Goniobranchus roboi appears in earth 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 Goniobranchus roboi 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: Goniobranchus roboi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Gastropods described in 1998, Goniobranchus, Molluscs of the Indian Ocean, so understanding it makes those chapters shorter.
In everyday life: Look for Goniobranchus roboi 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.
