The Gulf Cockle

The Gulf Cockle (Gulf of California)
The Gulf Cockle (Trachycardium panamense) is a beautiful, sturdy seashell found on beaches from the Gulf of California to Central America.
This heavy seashell is fairly easy to identify with its 20 +/- broad, strong, triangular radiating ribs and rather well-rounded shape. On the scalloped posterior edge of the shell, the ridges end in a sawtooth fashion. The exterior of this solid seashell is whitish in color, while the inside of the Gulf Cockle is somewhat smooth and white. Our specimens show a beautiful, purple-pink shading on the “teeth” side of the interior.
The hefty Gulf Cockle lives near the surface in sand or sandy mud in shallow water. This Pacific beauty can grow up to 4 inches in diameter.

About 200 species of cockles (family Cardiidae) are found worldwide. Strong and compact, this family of clams is heart-shaped when viewed from the side (with both valves intact).
We rate the Gulf Cockle: ♥♥♥♥♥

Thank you! We certainly love beaches, and we’re all nuts about beachcombing! 🙂

I like rocks, too. I gave away my collection when I left the classroom to another 4th grade teacher. I just love the different shapes and colors, some worn smooth, some sharp and jagged. mmmmm rocks!

Yay! My daughter and her husband are both geologists. I think we just like having any excuse to be out in the sand or dirt. It follows that rocks on the beach are the very best kind. 🙂

Thank you so much! Seashells and my grandkids are the very best subjects! Only the seashells will stay still for me though.

A beauty indeed….and your photography is awesome! I think I also saw something similar to this in tropical waters (i.e. Philippine waters). 🙂

Thank you so much! I’m sure you did see something very similar. I understand they’re quite popular around the world as food, too.

I used to have a Facebook page called Sandra’s Seashells on the Moon. My motto was: Hidden within every experience are gifts waiting to be uncovered. Like seashells embedded in sand, you have to seek them out. Your page is a hidden gift that I’m glad I found.
