Head anatomy of a lantern shark wet-collection specimen (Chondrichthyes: Etmopteridae). [PDF]
J Anat, 2023 In this study, we present a two‐step micro‐computed tomography array to a 39‐year‐old wet‐collection Lantern Shark specimen of Etmopterus lucifer. The focus of our scanning approach is the head anatomy showing numerous internal structures, for example the ampullae of Lorenzini, the olfactory system and major brain areas.
