Introduction
Post-embryonic change in morphology is a common feature of most organisms (e.g., Werner, 1988). Such ontogenetic modifications may affect the ecology of the organism (Calder, 1984; Werner, 1988; Stearns, 1992) and may provide insight into the evolution of form and function, yet they are often neglected in studies of functional morphology and comparative biomechanics. Significant effects on the life cycle of an organism need not involve dramatic alterations of morphology during ontogeny. For example, at hatching, cephalopod molluscs are broadly similar in form to adults (Boletzky, 1974; Sweeney et al., 1992). Yet these ...
