Linophryne andersoni

Linophryne andersoni 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 Linophryne andersoni rather than just read about it. In short: Linophryne andersoni is a species of marine ray-finned fish belonging to the family Linophrynidae, the leftvents, a group of deep water anglerfishes. This species is found in deep water northeast of the Line Islands.

Reference excerpt

Linophryne andersoni is a species of marine ray-finned fish belonging to the family Linophrynidae, the leftvents, a group of deep water anglerfishes. This species is found in deep water northeast of the Line Islands.

Taxonomy Linophryne andersoni was first formally described in 1992 by the South African ichthyologist Ofer Gon with its type locality given as northeast of the Line Islands at 11°49'N, 144°51'W from a depth of 0 to 50 m (0 to 164 ft). Within the genus Linophryne this species is placed within the subgenus Rhizophryne. The 5th edition of Fishes of the World classifies the genus Linophryne within the family Linophrynidae, which it places within the suborder Ceratioidei, the deep sea anglerfishes, within the order Lophiiformes, the anglerfishes.

Etymology Linophryne andersoni is a member of the genus Linophryne, a name which prefixes linos, which means "net", an allusion Collett did not explain when he proposed the genus, with phryne, meaning "toad". The prefix may be a reference to the sac like mouth hanging off the trunk, which in the holotype contained a lanternfish, like a fisherman's keep net. The second part phryne is commonly used in the names of anglerfish genera. Its use may date as far back as Aristotle and Cicero, who referred to anglerfishes as "fishing-frogs" and "sea-frogs," respectively, possibly because of their resemblance to frogs and toads. The specific name, andersoni, honours M. Eric Anderson, an ichthyologist at the J. L. B. Smith Institute of Ichthyology.

Description Linophryne andersoni is known only from the holotype which had 3 softrays in both the dorsal and anal fin. The holotype was a metamophosed female which had the following distinguishing characteristics. The bulb of the esca which is globular and has a low, rounded prolongation at its tip which has no appendages. The esca also has two pairs of appendages on its side towards the rear, the inner pair are short while the outer pair are less than half the diameter of the escal bulb and each has a clump of short filaments at its tip. the hyoid barbel is split near its base into a median and two lateral main branches. The caudal peduncle has a series of large subdermal melanophores on its lower side. The standard length of the holoptype was 3.2 cm (1.3 in).

Distribution, habitat and biology Linophryne andersoni is known only from its type locality, northeast of the Line Islands, and from only a single specimen so little is known of its distribution and life history.

Worked examples

Example 1 — a first encounter with Linophryne andersoni

Start with the simplest possible case. Write down what Linophryne andersoni 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 Linophryne andersoni 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 Linophryne andersoni 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 Linophryne andersoni

In research: Linophryne andersoni 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 Linophryne andersoni 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: Linophryne andersoni is common in secondary-school and first-year university syllabi. It links to neighbouring topics Deep sea fish, Fish described in 1992, IUCN Red List data deficient species, so understanding it makes those chapters shorter.
In everyday life: Look for Linophryne andersoni 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.
