Fig. 3From: Morphological disparity in extant and extinct sepiid phragmocones: morphological adaptions for phragmocone strength compared to those related to cameral liquid emptying hypothesesImplosion morphology of shallow, and deep-water sepiids. In shallow water forms, as illustrated by Sepia officinalis, implosion occurs along entire length of cuttlebone. In deep-water species, implosion occurs as sequential compression of latest chambersBack to article page
