The embryonic development of the centipede Strigamia maritima

► We provide the first detailed modern description of embryo development in a centipede. ► The species used, Strigamia maritima is the first myriapod to have a sequenced genome. ► This paper provides a standard reference for staging and a timeline for development. ► We show that cleavage is extremely prolonged, taking almost half of embryogenesis. ► We identify four phases of segment addition extending until just before hatching.
