... striated muscles and instead that length–force relationships vary with operating length range. To test these predictions, we measured length–force relationships of five obliquely striated muscles from inshore longfin squid, Doryteuthis pealeii : tentacle, funnel retractor and head retractor longitudinal...

... in a cephalopod, the two-toned pygmy squid ( Idiosepius pygmaeus ). We exposed squid to ambient (∼450 µatm) or elevated (∼1000 µatm) CO 2 for 7 days. Squid were treated with sham, the GABA A receptor antagonist gabazine or the non-specific GABA A receptor antagonist picrotoxin, before measurement of conspecific...

... and neural responses to tissue injury in the sepiolid Euprymna scolopes (Hawaiian bobtail squid), which inhabits shallow tropical waters close to dense human habitation. Behavioral hypersensitivity and neural plasticity that occur normally after tissue injury were impaired both under chronic estrogen...

...Andrew M. Smith; Scott M. LaValva; Matthew M. Loiacono; Joseph T. Thompson ABSTRACT We have discovered features of the nuchal joint in the squid, Doryteuthis pealeii , that are unique compared with moveable joints in other animals. The joint's function is unclear but it allows the head to glide...

...Rachel A. Jastrebsky; Ian K. Bartol; Paul S. Krueger ABSTRACT Although squid are generally considered to be effective predators, little is currently known of how squid maneuver and position themselves during prey strikes. In this study, high-speed video and kinematic analyses were used to study...

...Carly A. York; Ian K. Bartol; Paul S. Krueger ABSTRACT Squid rely on multiple sensory systems for predator detection. In this study we examine the role of two sensory systems, the lateral line analogue and vision, in successful predator evasion throughout ontogeny. Squid Doryteuthis pealeii...

...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...

...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...
