It has been Cephalopoda suggested that ancestral ommastrephids inhabited coastal waters and expanded their distribution into the open Evolution ocean during global changes in ocean circulation in the Oligocene. This hypothesis could explain the diﬀerent Reproduction reproductive strategies in oceanic squids, but has never been tested in a phylogenetic context. In the present Ancestral states study, we assess the coastal-to-open-ocean hypothesis through inferring the evolution of reproductive traits Divergence times (spawning type) of ommastrephid squids using the phylogenetic comparative method to estimate
