Crassispira coelata is a species of small predatory sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, within the superfamily Conoidea. It was originally described by Richard Brinsley Hinds in 1843.
Taxonomy and Classification
Crassispira coelata belongs to the following taxonomic hierarchy:
- Kingdom: Animalia
- Phylum: Mollusca
- Class: Gastropoda
- Subclass: Caenogastropoda
- Order: Hypsogastropoda
- Superfamily: Conoidea
- Family: Pseudomelatomidae
- Genus: Crassispira
- Species: Crassispira coelata
The species was initially described under the name Pleurotoma coelata by Hinds. Over time, taxonomic revisions led to its reclassification within the genus Crassispira. The family Pseudomelatomidae is one of several families that have been split from the broader (and now obsolete) family Turridae, reflecting a more refined understanding of conoidean phylogeny.
Description
Members of the genus Crassispira typically possess shells that are fusiform (spindle-shaped) to biconic, characterized by strong axial and spiral sculpture. A distinctive feature of Crassispira species, including C. coelata, is the presence of a well-defined anal sinus on the outer lip of the aperture, which is a key characteristic of Conoidea snails. The siphonal canal is usually short.
For Crassispira coelata, the specific epithet "coelata" (from Latin coelatus, meaning "chiseled" or "carved") likely refers to the detailed and often intricate shell sculpture. While specific measurements vary, these are generally small to medium-sized gastropods. The shell often exhibits a glossy appearance and may display various color patterns, though specific descriptions for C. coelata emphasize its sculptural characteristics.
Distribution and Habitat
Crassispira coelata is native to the Eastern Pacific Ocean. Its distribution includes the tropical and subtropical waters off the Pacific coast of Central America, with specific records from the Gulf of Panama, particularly the region of ChiriquÃ.
As a marine gastropod, Crassispira coelata inhabits benthic environments, typically found on the seabed in shallow to moderate depths. Like other members of the Conoidea, it is a predatory snail, likely feeding on small invertebrates, though specific dietary details for this species are not extensively documented.
