Cerithidea moerchii is a species of small to medium-sized sea snail, a marine gastropod mollusc in the family Potamididae. This species is a common inhabitant of intertidal and estuarine environments, particularly in mangrove ecosystems.
Description & Characteristics
Cerithidea moerchii typically grows to a maximum size of around 30 mm in length. The shell of Cerithidea moerchii is characterized by its elongated, spire-shaped form with numerous whorls. The shell’s surface is often smooth or slightly textured, and the aperture (opening) is typically oval-shaped. The coloration of the shell can vary but often displays shades of brown, grey, or white.
Habitat and Occurrence
Cerithidea moerchii is predominantly found in intertidal and estuarine environments, particularly in mangrove ecosystems. These snails are well-adapted to the fluctuating salinity and temperature conditions common in these habitats. They typically inhabit areas of soft sediment, such as mud or sand, and may also be found on rocky surfaces. The distribution of Cerithidea moerchii extends across various marine zones, encompassing both the intertidal and subtidal regions.
Taxonomy
Cerithidea moerchii belongs to the Class Gastropoda, which encompasses a wide range of snails and slugs. This species is further classified within the Order Caenogastropoda incertae sedis, a group of snails exhibiting a diverse array of characteristics. Cerithidea moerchii is a member of the Family Potamididae, a group of snails known for their association with estuarine and intertidal habitats.
Feeding
Cerithidea moerchii is a herbivorous snail that primarily feeds on algae, detritus, and other organic matter. They use their radula, a rasping tongue-like structure, to scrape food particles from surfaces. The feeding habits of Cerithidea moerchii contribute to the nutrient cycling within their ecosystems.
