Ammidae

Ammidae is a family of marine snails, specifically belonging to the order Littorinimorpha. These gastropod mollusks are characterized by their generally small to medium-sized shells, which are often conical or ovate in shape. The shell surface can vary from smooth to sculptured, with many species exhibiting ribs or axial lines. The aperture of the shell is typically oval or round, and the operculum, a protective plate that seals the shell opening, is usually corneous and paucispiral.

Members of the Ammidae family are found in marine environments worldwide, with a particular abundance in tropical and subtropical regions. They are benthic organisms, meaning they live on the seafloor. Their habitats are diverse, ranging from shallow intertidal zones and rocky shores to deeper subtidal areas and even coral reefs. Ammidae are typically herbivores or detritivores, feeding on algae, diatoms, or organic matter found on substrates. Reproduction in Ammidae, as in many marine gastropods, often involves external fertilization, with larvae developing and dispersing in the plankton. While not extensively studied for commercial purposes, some species may be consumed locally in certain coastal communities. The taxonomy and classification of Ammidae continue to be refined through ongoing research in malacology.
