Cerodrillia brunnea is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. These are predatory, small to medium-sized sea snails.
Taxonomy The species Cerodrillia brunnea was formally described by Charles Marcus Cooke in 1943. It belongs to the following taxonomic classification:
- Kingdom: Animalia
- Phylum: Mollusca
- Class: Gastropoda
- Subclass: Caenogastropoda
- Order: Neogastropoda
- Superfamily: Conoidea
- Family: Drilliidae
- Genus: Cerodrillia
- Species: C. brunnea
Description Like other members of the Drilliidae family, Cerodrillia brunnea typically possesses a shell that is relatively small, often elongated, and characterized by a prominent aperture. Specific details on the shell morphology of C. brunnea include a brownish coloration (as suggested by the specific epithet "brunnea," meaning brown) and sculpturing common to the genus Cerodrillia, which may include axial ribs and spiral cords. Its radula is adapted for a predatory lifestyle, allowing it to feed on other small invertebrates.
Distribution and Habitat Cerodrillia brunnea is known to inhabit marine environments, specifically in regions such as Hawaii, where it was originally described. It is a benthic species, meaning it lives on or near the seabed, typically in tropical or subtropical waters. Its exact depth range and specific microhabitat preferences would be consistent with other members of its genus, often found in sandy or muddy substrates.
