From: Global biogeography and evolution of Cuvierina pteropods
Centroid size variation for reference museum specimens of Cuvierina in ventral (N = 712) and apertural (N = 352) orientations. Typical specimens of six morphotypes are shown with outlines transformed to semi-landmarks to allow for geometric morphometric analysis. Lengths of Cuvierina shells were between 0.6 and 1.1 cm.
