Fig. 10. Schematic diagram of the major changes in coasting dynamics over ontogeny. Larval (A) and juvenile (B) stages operate in the viscous regime (symbolized by a blue flow gradient), whereas the adult stage (C) operates in an in inertial regime (denoted by the blue streamlines). Despite this change in hydrodynamics, it is primarily the body mass (orange circle) and initial speed (grey arrow) that cause the observed differences in coasting performance (Fig. 4).
