Identification Guide

The Giant Cockle, or Laevicardium elatum, has distinct features that make it recognizable. Knowing how to identify this bivalve can help in understanding its ecology and habitat. Below are detailed descriptions of how to recognize this species and how it compares to similar species.

How to Identify a Giant Cockle

To identify a Giant Cockle, look for its characteristic shell shape. The shell is typically smooth and rounded, resembling an egg. The size can vary, but it generally measures about 8 to 15 cm in diameter.

The color of the shell tends to be light yellow to cream with subtle markings. The hinge area shows small, fine teeth. Additionally, the absence of distinct ridges or bumps is important for identification.

When alive, the clam’s siphons extend from the shell, appearing prominently. Checking for these features can confirm if a specimen is Laevicardium elatum.
