Summary: | (A) N . coriiceps during an S-bend maneuver shown at 33 ms intervals (at +11.05°C). (B) N . coriiceps during a C-bend turn shown at 100 ms intervals (at +12.4°C). (C) C . aceratus during a C-bend turn shown at 100 ms intervals (at +8.5°C). (D) C . aceratus during a withdrawal-like maneuver shown at 100 ms intervals (at +11.5°C). In all panels, ventral views (pectoral fins not shown) are depicted. Gray vertical arrows indicate the position of the midline at the beginning of turning maneuvers. Arrow diagrams on the right depict of the head orientation during turns, at time intervals indicated above. Each arrow connects the position of the fish nose with the center of mass.
