Reference excerpt

The New Caledonian sea krait (Laticauda saintgironsi) is a species of venomous snake in the subfamily Laticaudinae of the family Elapidae. The species is native to the waters around New Caledonia.

Etymology The specific name, saintgironsi, is in honor of French herpetologist Hubert Saint Girons.

Geographic range L. saintgironsi is endemic to New Caledonia, including the Loyalty Islands. It is very rarely found outside of its native range (one specimen was found in New Zealand in 1925), likely due to Laticauda species tending to spend time onshore or in shallow water, limiting their chance to encounter oceanic currents.

Habitat The natural habitats of L. saintgironsi are marine, intertidal, and supratidal, from a depth of 80 m (260 ft) to an altitude of 100 m (330 ft).

Description L. saintgironsi exhibits sexual dimorphism, with females growing larger than males. Maximum recorded snout-to-vent length (SVL) for a male is 81.7 cm (32.2 in). Maximum recorded SVL for a female is 109 cm (43 in). The upper lip is yellow or cream-colored, and the rostral scale is undivided. Specimens can be identified by this yellow upper lip, which is present in both this species and the Yellow-lipped sea krait, and the presence of 21 rows of mid-body scales, compared to the yellow-lipped sea krait's 23 banded rows that meet ventrally.

Diet The diet of L. saintgironsi consists of non-spiny anguilliform fishes, with the lipspot moray Gymnothorax chilospilus representing about half of the prey.

Parasites Only a few parasites have been recorded for the New Caledonian sea krait, including camallanid nematodes.

Reproduction L. saintgironsi is oviparous.

Worked examples

Example 1 — a first encounter with New Caledonian sea krait

Start with the simplest possible case. Write down what New Caledonian sea krait 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 New Caledonian sea krait 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 New Caledonian sea krait 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 New Caledonian sea krait

In research: New Caledonian sea krait 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 New Caledonian sea krait 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: New Caledonian sea krait is common in secondary-school and first-year university syllabi. It links to neighbouring topics IUCN Red List least concern species, Laticauda, Reptiles described in 2006, so understanding it makes those chapters shorter.
In everyday life: Look for New Caledonian sea krait 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.
