Schematic summary of the main events during the embryonic formation of the octopus arm. Arms are illustrated in an oral view with proximal to the left. Octopus arm formation can be divided into distinct developmental phases, each corresponding to specific developmental events. Early embryonic development establishes the arm, which switches to an adult type of growth once the main tissue types have differentiated. Abbreviations: gza, growth zone of the arm.
