Gigantopecten latissimus has a shell reaching a height of about 134 millimetres (5.3 in) and a length of about 167 millimetres (6.6 in). This shell is thick and biconvex. The left valve is slightly more convex than the right one. The outer surface of the right valve has six shallow radial ribs that are rectangular in cross-section, while the left valve shows five radial ribs on the external surface. Both valves have distinct concentric growth striae.[1]
