"Anomia ephippium" refers to a species of bivalve mollusk that belongs to the family Anomiidae. This species is commonly known as the saddle oyster due to the distinct saddle-like shape of its shells.
The shell of Anomia ephippium is thin, fragile, and irregularly shaped, typically growing up to 6 cm in length. It has a biconvex structure, meaning that both the upper and lower sides are convex. The exterior of the shell is covered in fine concentric ridges and grooves, while the inner surface is smooth and shiny. The coloration of the shell can vary, but it is usually pale or whitish, occasionally displaying subtle shades of pink or yellow.
Anomia ephippium is primarily found in shallow coastal waters of the northeastern Atlantic Ocean, ranging from Portugal to Norway. It is commonly found attached to various substrates such as rocks, shells, or other hard surfaces. This species has a remarkable ability to attach itself using byssal threads produced by a specialized gland, allowing it to withstand high wave action and turbulent waters.
Being a filter feeder, Anomia ephippium utilizes its unique anatomy to extract plankton and other tiny organisms from seawater through its gills. It plays a significant role in marine ecosystems by improving water quality and providing a food source for various predators.
Due to their peculiar saddle-like shells, Anomia ephippium shells are frequently collected by beachcombers and shell enthusiasts. They are also of interest to researchers, contributing to the study of biodiversity, ecology, and evolution of marine organisms.
