Acanthocardia echinata is a species of bivalve mollusk belonging to the family Cardiidae, commonly known as cockles. This marine species is distinctive for its robust, heart-shaped shell, which can be found along the coastal regions of the Comunidad Valenciana.

The shell of Acanthocardia echinata is identifiable by its thick and slightly elongated form with pronounced radial ribs covered with spines. The external color of the shell can range from cream to light brown, often exhibiting darker bands or spots.

Characteristics:

• Habitat: Typically found buried in sandy or muddy substrates in shallow waters, often in areas with sea grass.
• Size: The shell can grow up to 6 cm in length, making it a large member of the cockle family.
• Diet: This species is a filter feeder, consuming plankton and organic particles suspended in the water.
• Reproduction: Like many bivalves, Acanthocardia echinata is capable of both sexual and asexual reproduction, releasing larvae into the water which later settle and develop into adult forms.

In the Comunidad Valenciana, this species is not only valued for its ecological role in marine ecosystems but also holds gastronomic importance. Locally, it may be referred to as the "berberecho espinoso" due to its spiny exterior, and it can be a part of traditional dishes, enjoyed for its rich flavor.
