Mollusca Anomia ephippium, commonly known as the Saddle Oyster or locally referred to as Ostra de Montura, is a fascinating species of bivalve mollusk that inhabits the marine environments of the Comunidad Valenciana and beyond. Known for its unique shell shape, this species is an intriguing part of the local marine biodiversity.

The shell of Anomia ephippium is characterized by its irregularly rounded, thin, and translucent appearance with a noteworthy attachment area, giving it a saddle-like form. This feature allows the mollusk to adapt to various surfaces in the marine habitat.

• Habitat: This species is typically found attached to rocks, shells, or other hard surfaces underwater, from shallow waters to depths of around 200 meters. It thrives in both coastal and offshore regions within the Mediterranean.
• Size: The shell size of Anomia ephippium usually ranges from 2 to 5 centimeters in diameter, making it a small but distinctive part of the seaside landscape.
• Coloration: Its shell often displays a range of colors including cream, yellowish, and brown hues, sometimes with light iridescent reflections that add to its aesthetic value.
• Feeding: The Saddle Oyster is a filter feeder, playing a crucial role in the aquatic ecosystem by filtering plankton and organic particles from the water, thereby maintaining water quality.
• Reproduction: Reproduction occurs via external fertilization, where eggs and sperm are released into the water column, leading to the development of free-swimming larvae.

In summary, Anomia ephippium is not just a simple shell but a remarkable species that contributes significantly to marine ecosystems. Understanding its presence and role within the Comunidad Valenciana highlights the area's rich marine heritage and underscores the importance of conserving these unique habitats.
