Cominella elegantula is a species of sea snail, a marine gastropod mollusk in the family Cominellidae. This species, also known as the “elegant Cominella,” is a common and easily identifiable inhabitant of various coastal regions.
Description & Characteristics
Cominella elegantula is a medium-sized snail, typically reaching a maximum size of around 30 millimeters. Its shell exhibits a distinctive conical shape, with a pointed spire and a wide, rounded aperture. The shell surface is usually smooth and glossy, often displaying a variety of colors ranging from pale beige to shades of brown and orange. The aperture is characterized by a distinct siphonal canal, which extends outwards from the base of the shell.
Habitat and Occurrence
Cominella elegantula is a species found in the intertidal zone and shallow subtidal waters. It prefers habitats with a mix of sand, gravel, and rocky substrates. This species can be found in both the infralittoral zone, the area that extends from the low tide mark to a depth of around 20 meters, and the circalittoral zone, which spans from depths of approximately 20 meters to around 200 meters. This wide depth range reflects its adaptability to varying environmental conditions.
Taxonomy
Cominella elegantula belongs to the class Gastropoda, a diverse group of mollusks that includes snails, slugs, and nudibranchs. This species falls within the order Neogastropoda, which comprises carnivorous and predatory gastropods. Cominella elegantula is further classified within the family Cominellidae, a family known for its characteristic conical shells and predatory feeding habits.
Feeding
Cominella elegantula is a carnivorous predator, feeding primarily on other mollusks, worms, and crustaceans. Its diet consists mainly of small, soft-bodied invertebrates that it hunts using its sharp radula, a specialized tongue-like structure covered with teeth. This predatory behavior is a common characteristic of the family Cominellidae, contributing to the ecological balance within its habitat.
