This section of CephRes website is dedicated to “J.Z. Young work and its legacy” as sign of the significant and important results that his work promoted. We also recognize the very large number of scientific works that various scientists visiting the Stazione Zoologica Anton Dohrn in Napoli (before JZ) produced around octopus and other cephalopods, thus providing a boost to the study of the biology of cephalopod mollusks everywhere.
