Bayesian ancestral state reconstruction of cephalopod habitat distribution. Tree from Tanner et al., (2017) based on transcriptomic data. Pie charts at nodes represent posterior probabilities of states. Coastal habitats are essentially restricted to the photic zone, while pelagic species are either vertical migrants or deep-sea inhabitants. Note the independent secondary invasion of the pelagic habitat within decabrachians and the shift from pelagic to coastal habitat within octobrachians
