Definition
Mangelia coarctata is the scientific name of a marine gastropod mollusk that has been placed within the genus Mangelia of the family Mangeliidae.
Overview
The name appears in taxonomic listings of sea snails, but comprehensive information regarding its morphology, geographical distribution, ecological habits, and taxonomic status is scarce in widely accessible, peer‑reviewed literature. Consequently, the species is not prominently featured in major marine biodiversity databases.
Etymology / Origin
The generic name Mangelia derives from the Latin “mangelia,” historically used for certain small, slender shells, and is a longstanding term in malacology. The specific epithet coarctata is Latin for “narrow” or “compressed,” likely referring to a characteristic of the shell shape, such as a constricted or tightly coiled form.
Characteristics
- Shell morphology: As implied by the epithet, the shell is presumed to be relatively narrow or tightly coiled, consistent with many Mangelia species that possess elongate, turreted shells with distinct axial ribs and spiral sculpture.
- Size: Species of Mangelia typically range from a few millimetres to about two centimetres in length; precise measurements for M. coarctata are not documented in readily available sources.
- Habitat: Members of Mangeliidae are marine predators inhabiting sandy or muddy substrates, often from shallow subtidal zones to deeper waters. Specific habitat data for M. coarctata are not confirmed.
- Distribution: No definitive distribution records have been established for M. coarctata in major biogeographic databases; any geographic range remains uncertain.

Accurate information is not confirmed for many aspects of Mangelia coarctata due to the limited availability of detailed, reliable references.
