Descrição: The ligament in Laternula is modified into a complex mechanical structure composed of rigid and flexible parts with multiple connection points. Rather than allowing the valves to move with respect to each other, this ligament tends to keep them immobile. Providing space inside the shell for the modified ligament requires a secondary increase in shell curvature of the umbones. This is achieved by the shell flexing by muscular contraction and stiffening while flexed through the construction of a rigid buttress. A vertical slit in each valve, produced by secondary resorption and breakage of shell material, confines mechanical stress to the posterior slope of the shell.
