...Iman Borazjani SUMMARY Fast starts are crucial in the survival of aquatic swimmers to capture prey or avoid predators. Currently, it is widely accepted that during C-starts: (1) the caudal fin generates a considerable hydrodynamic force; and (2) anal/dorsal fins are erected to significantly...

...William J. Stewart; Ian K. Bartol; Paul S. Krueger SUMMARY Although the pulsed jet is often considered the foundation of a squid's locomotive system, the lateral fins also probably play an important role in swimming, potentially providing thrust, lift and dynamic stability as needed. Fin morphology...

...David Lentink; Michael H. Dickinson SUMMARY Organisms that swim or fly with fins or wings physically interact with the surrounding water and air. The interactions are governed by the morphology and kinematics of the locomotory system that form boundary conditions to the Navier–Stokes (NS) equations...

... to new insights in the study of aquatic propulsion. We use two examples: (1) pectoral fin function, and (2) hydrodynamic interactions between dorsal and caudal fins. Pectoral fin function is characterized by considerable deformation of individual fin rays, as well as spanwise (along the length...

...P. Zamparo; D. R. Pendergast; B. Termin; A. E. Minetti SUMMARY The aim of the present study was to quantify the improvements in the economy and efficiency of surface swimming brought about by the use of fins over a range of speeds ( v ) that could be sustained aerobically. At comparable speeds...

... in the mantle of Octopus ( Sereni & Young, 1932 ) and Eledone ( Alexandrowicz, 1960 ). While there is good physiological evidence for the existence of mechanoreceptors in the mantle of Octopus ( Gray, 1960 ; Wilson, 1960 ; Boyle, 1976 ), mechanoreception in the mantle and fins of decapods has not been...
