    • ‘While boxfishes have the ability to complete 360 [degrees] turns with turning radii of effectively zero, these turns are relatively slow (100 [degrees] / sec/total length) but with larger radii.’
    • ‘In most of the boxfishes, vortex circulation increased from the posterior 3/4 of the carapace to the posterior edge of the carapace, but surface pressures along the carapace did not decrease.’
    • ‘Squid, barracuda, and grouper were prevalent, as were French and Queen angelfish, small parrotfish, trumpet, and boxfishes.’

    • ‘Like its relative the puffer fish, the boxfish propels itself by waving its dorsal fin (on top of its body) and its anal fin (on the bottom), and it steers primarily with its pectoral fins and tail fin.’
    • ‘Control for pitching is important for fish, such as boxfishes, that live in highly energetic waters with frequent external disturbances like turbulence.’
    • ‘Although differences in carapace morphology were apparent, vortical flow patterns around the four boxfishes were fairly consistent.’
    • ‘The boxfish, for example, is an aquatic tank with two bony skeletons, one on the inside to support its innards and one on the outside to deter predators.’
