... feeding in at least one body location in one fish. If fish bodies also deform like beams during dorsoventral feeding motions, this would suggest the dorsal body (epaxial) muscles must homogenize both dorsoventral and mediolateral strain gradients. We tested this hypothesis by measuring curvature...

...Ariel L. Camp; Aaron M. Olsen; L. Patricia Hernandez; Elizabeth L. Brainerd ABSTRACT Some fishes rely on large regions of the dorsal (epaxial) and ventral (hypaxial) body muscles to power suction feeding. Epaxial and hypaxial muscles are known to act as motors, powering rapid mouth expansion...

... to as intervertebral fibers IV-1 and IV-2( Auffenberg, 1959 ). The m. dorsalis trunci (DT) forms the bulk of the epaxial muscle mass and is segmented throughout the trunk by myosepta, which attach to the neural spines and the transverse processes of the vertebrae and follow a peculiar,complex course. Within...
