The development of several cephalopods among them Sepia officinalis (Linnaeus, 1758) has been very carefully described by Naef in the early 20th century. Here an illustrated developmental table of Sepia officinalis is proposed with a morphological description of each stage. The 30 stages are grouped into five steps of development: cleavage (stages 1 to 9), gastrulation (stages 10 to 13), organogenesis, plane phase (stages 14 to 18), organogenesis, extension phase (stages 19 to 22) and organogenesis, growth phase (stages 23 to 30), when the embryo has acquired the general adult conformation. For each stage, morphological identification criteria are proposed in order that this table is used as a lab tool for cephalopod researchers interested in development.
