What is the structural purpose of the radial ribs on a cockle shell?

Answer

They provide structural integrity and distribute pressure efficiently.

The radial ribs extend from the umbo to the margin, providing inherent engineering that allows the shell to withstand physical forces exerted by wave action and shifting substrates.
