...Hawkins J. Dowis; Chugey A. Sepulveda; Jeffrey B. Graham; Kathryn A. Dickson SUMMARY The swimming kinematics of the eastern Pacific bonito Sarda chiliensis at a range of sustained speeds were analyzed to test the hypothesis that the bonito's swimming mode differs from the thunniform locomotor mode...

...Jeanine M. Donley; Kathryn A. Dickson ABSTRACT The swimming kinematics of two active pelagic fishes from the family Scombridae were compared to test the hypothesis that the kawakawa tuna ( Euthynnus affinis ) uses the thunniform mode of locomotion, in which the body is held more rigid and undergoes...

... length) is 30–60% longer than in other cruise-adapted teleosts such as salmonids. The resulting thunniform swimming mode and the morphological and anatomical adaptations associated with the long propulsive wavelength (e.g. fusiform body shape, rigid vertebral column) act to minimize anterior resistance...
