..., the vertical and horizontal septa and the peritoneum ( Vogel and Gemballa, 2000 ; Westneat et al., 1993 ). A vertical septum composed of cross-woven collagen fibers encloses both the neural spines of the vertebral column and the pterygiophores of the fins. (B) Cross-sectional views of a fish at different...

...Peggy Gerullis; Caroline P. Reinel; Stefan Schuster ABSTRACT Archerfish down a variety of aerial prey from a range of distances using water jets that they adjust to the size and distance of their prey. We describe here that characteristic rapid fin maneuvers, most notably of the pectoral and pelvic...

...Andrew B. George; Mark W. Westneat ABSTRACT Triggerfishes and filefishes (Balistoidea) use balistiform locomotion to power steady swimming with their dorsal and anal fins, and transition to a gait dominated by body and caudal fin (BCF) kinematics at high speeds. Fin and body shapes are predicted...

...Ian K. Bartol; Paul S. Krueger; Carly A. York; Joseph T. Thompson ABSTRACT Squid, which swim using a coupled fin/jet system powered by muscular hydrostats, pose unique challenges for the study of locomotion. The high flexibility of the fins and complex flow fields generated by distinct propulsion...

...Frank E. Fish; George V. Lauder ABSTRACT Aquatic vertebrates display a variety of control surfaces that are used for propulsion, stabilization, trim and maneuvering. Control surfaces include paired and median fins in fishes, and flippers and flukes in secondarily aquatic tetrapods. These structures...

...Kara L. Feilich ABSTRACT Comparative studies of fish swimming have been limited by the lack of quantitative definitions of fish gaits. Traditionally, steady swimming gaits have been defined categorically by the fin or region of the body that is used as the main propulsor and named after major fish...
