Dosinia lupinus is a species within the phylum Mollusca, commonly found in marine environments. This bivalve mollusk is part of the family Veneridae and is known for its rounded, smooth shell, which is often a delicate cream or light brown color. The shell's surface features subtle concentric ridges that add to its distinctive appearance.

In the Comunidad Valenciana, Dosinia lupinus is typically found in sandy or muddy substrates of shallow coastal waters. Its behavior is characterized by burrowing into the substrate, where it uses its siphons to filter feed, extracting nutrients from the suspended particles in the water.

Key features of Dosinia lupinus include:

• Shell diameter typically ranges from 4 to 6 centimeters.
• The shell is equivalve, meaning both halves (valves) are of equal size.
• The interior of the shell is usually glossy and may exhibit a hint of pink or purple hues near the hinge.
• The animal uses a muscular foot to dig and anchor itself within the substrate.

This species is often referred to by its local name, which is commonly recognized by those familiar with the region's marine life.
