What kinematic and hydrodynamic turning capabilities do hatchling cuttlefish Sepia officinalis and Sepia bandensis employ and how do they compare with squid Doryteuthis pealeii paralarvae?
Most cephalopods hatch out at about 1-5% of their adult body length. As swimmers develop, they experience different flow regimes and undergo vast morphological changes, thus understanding how turning capabilities change with ontogeny is critical for a comprehensive understanding of maneuverability. Currently, there are no kinematic or wake-based analyses of turning cephalopods at any life history stage, thus it is unclear if fin and jet flows observed during rectilinear swimming translate to turning motions. |
