Microstructural insights into the functional morphology and formation logic of spherulitic–fibrous prismatic architecture in the shell–like eggcase of the argonaut octopods

Abstract Argonautid octopods (genus Argonauta) possess a unique shell-like biomineralized eggcase, which was suggested to be produced by the first dorsal arms rather than by the mantle tissue, as in typical molluscan shells. In this study, we conducted scanning electron microscopy to investigate the...
