Cephalopod Orientation

During the early evolution of cephalopods, dorsoventral axis elongated. This axis became the functional anterior-posterior axis. The anterior-posterior axis of their ancestors shortened and became the functional dorsoventral axis. In the figure given below, morphological orientation is labelled in red coloured lower cased words while the functional orientation is labelled in green coloured UPPERCASED words.
