Turbo cornutus
species of mollusc
Turbo cornutus, common name the horned turban, is a species of sea snail, marine gastropod mollusk in the family Turbinidae.
Description
The scientific name Turbo cornutus, literally means "horned turban," and it is characterized by a hard, ventricose, spiny, imperforate shell of which the length varies between 65 and 120 mm (2+1⁄2 and 4+3⁄4 in). It has a large, thick, green-gray shell with irregular incremental striae and spiral lirae. The shell has about 5–6 whorls, which turn clockwise and have horny protuberances. The body whorl is ventricose, somewhat bicarinate, armed about the middle with two spiral series of erect tubular spines, and frequently a smaller accessory row above. The lower series of spines is sometimes absent. The thickness and shape of the shell and the horns vary greatly according to environmental conditions. The sutures are deeply impressed. The oblique aperture is rounded and is about 3.5 cm (1+3⁄8 in) in diameter, and is green or red-brown. The thin inside lip of the shell is not smooth, but rough and granular.
Begin with the source’s own compact description: “Turbo cornutus” is species of mollusc. The dossier treats that line as a proposition to test through Turbo, cornutus and species, not as a finished interpretation.
Why this record matters
The phrase “species of mollusc” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q1038742. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
