The Cone-shaped Top Shell, Cone-shaped Top Sanil, scientifically known as Rochia conus, is a marine gastropod mollusk belonging to the family Tegulidae. This species is characterized by its distinctive cone-shaped shell, which has earned it its common names. It is a relatively small gastropod, commonly found in intertidal and shallow subtidal zones.
Description & Characteristics
The Rochia conus shell exhibits a conical shape, with a pointed apex and a wide base. The shell surface is typically smooth or slightly granular, and it can display a variety of colors, including brown, gray, and white. The shell size varies depending on the individual, with maximum sizes reaching up to a few centimeters in length. The aperture of the shell is relatively small and rounded, and the operculum, a protective plate covering the opening, is present. The soft body of the Rochia conus is adapted for crawling and feeding. It possesses a muscular foot that allows it to move along surfaces, and a radula, a ribbon-like structure with teeth, for scraping algae off surfaces.
Habitat and Occurrence
The Rochia conus is a marine gastropod, inhabiting intertidal and shallow subtidal zones. This species is commonly found on rocky shores, seawalls, and other hard substrates. Its distribution spans various marine zones, including the intertidal, infralittoral, and circalittoral zones, indicating its adaptability to different depths and environmental conditions.
Taxonomy
The Cone-shaped Top Shell, Cone-shaped Top Sanil, Rochia conus, belongs to the Class Gastropoda, Order Trochida, and Family Tegulidae. This classification places it within a group of marine snails known for their distinctive conical or top-shaped shells. This group is highly diverse, encompassing a variety of species with varying sizes, shapes, and colors.
Feeding
The Rochia conus is an herbivorous gastropod, primarily feeding on algae. It is an algae grazer, scraping algae off surfaces using its radula. It also feeds on epiphytes, organisms that grow on other plants or surfaces. This dietary preference makes the Rochia conus an important part of the marine ecosystem, helping to control algae populations and maintain ecological balance.
