...Danna J. Staaf; William F. Gilly; Mark W. Denny Squid are the largest jet propellers in nature as adults, but as paralarvae they are some of the smallest, faced with the inherent inefficiency of jet propulsion at a low Reynolds number. In this study we describe the behavior and kinematics...

.... Pelagic squid (like D. gigas ) that routinely depend on jet propulsion optimize their locomotory apparatus by pushing a large water volume through their mantle cavity, reducing oxygen extraction efficiency (5–10%) ( Pörtner, 1994 ; Wells et al., 1988 ). In contrast, nekton-benthic cephalopods (i.e...
