A key evolutionary transformation of the locomotor system of ray-finned fishes is the morphological elaboration of the dorsal fin. [...] Key Method Digital particle image velocimetry was used to visualize wake structures and to calculate in vivo locomotor forces. Study of the vortices generated simultaneously by the soft dorsal and caudal fins during locomotion allowed experimental characterization of median-fin wake interactions.Expand
Wake Dynamics and Locomotor Function in Fishes: Interpreting Evolutionary Patterns in Pectoral Fin Design1
TLDR
It is found that the pectoral fins of sunfish generate significantly higher forces for turning and direct braking forces closer to the center of mass of the body than the pectoral fins of trout. Expand
Functional morphology of the fin rays of teleost fishes
TLDR
This work examined the range of motion and curvatures of the pectoral fin rays of bluegill sunfish during steady swimming, turning maneuvers, and hovering behaviors and during a vortex perturbation impacting the fin during the fin beat, suggesting flexibility may offer intrinsic damping of environmental fluid perturbations encountered by swimming fish. Expand
Experimental Hydrodynamics and Evolution: Function of Median Fins in Ray-finned Fishes1
TLDR
Two recent technical developments in DPIV methodology are summarized: high-resolution DPIV using a recursive local-correlation algorithm allows quantification of small vortices, while stereo-DPIV permits simultaneous measurement of x, y, and z flow velocity components within a single planar light sheet. Expand
Structure of supporting elements in the dorsal fin of percid fishes
TLDR
It is hypothesized that fishes with separated dorsal fins, especially those with large gaps between fins, would have stiffened fin elements at the leading edge of the soft dorsal fin to resist hydrodynamic loading during locomotion. Expand
Fish locomotion: kinematics and hydrodynamics of flexible foil-like fins
The fins of fishes are remarkable propulsive devices that appear at the origin of fishes about 500 million years ago and have been a key feature of fish evolutionary diversification. Most fishExpand
Dorsal fin function in spiny dogfish during steady swimming
TLDR
Evidence is provided that spiny dogfish control movements of the first dorsal fin during steady swimming to stabilize body position, and the second dorsal fin appears to be capable of thrust generation. Expand
Hydrodynamic function of dorsal fins in spiny dogfish and bamboo sharks during steady swimming
TLDR
The generality of this hypothesis is evaluated by using time-resolved particle image velocimetry to record water flow patterns in the wake of both the anterior and posterior dorsal fins in two species of freely swimming sharks, suggesting that the first dorsal fin in spiny dogfish has primarily a stabilizing function, while the second dorsal fin has a propulsive function. Expand
Dorsal and anal fin function in bluegill sunfish Lepomis macrochirus: three-dimensional kinematics during propulsion and maneuvering
TLDR
It is found that dorsal and anal fins begin oscillating, in phase, at steady swimming speeds above 1.0 TL s–1 and that maximum lateral displacement of the trailing edge of the fins as well as fin area increase with increasing steady swimming speed, suggesting that fish have a high level of control over fin surface shape. Expand
Locomotor function of the dorsal fin in rainbow trout: kinematic patterns and hydrodynamic forces
TLDR
This study provides the first experimental evidence that the plesiomorphic soft dorsal fin of ray-finned fishes acts as an ancillary force generator during axial locomotion, and suggests that the distinction often made between median and paired fin propulsion and body and caudal fin (BCF) propulsion in fishes obscures the important role of multiple propulsors acting in a coordinated fashion. Expand
Hydrodynamic function of dorsal and anal fins in brook trout (Salvelinus fontinalis)
TLDR
The hydrodynamics of trout anal fin function is examined and it is hypothesized that anal fins, located below the fish's rolling axis, produce similar jets to the dorsal fin and help balance rolling torques during swimming. Expand

Function of the Caudal Fin During Locomotion in Fishes: Kinematics, Flow Visualization, and Evolutionary Patterns1
TLDR
Two experimental approaches are reviewed which promise to provide new insights into the function and evolution of the caudal fin: three-dimensional kinematic analysis, and quantitative flow measurements in the wake of freely-swimming fishes using digital particle image velocimetry (DPIV). Expand
Function of the dorsal fin in bluegill sunfish: Motor patterns during four distinct locomotor behaviors
TLDR
Cumulative data from all four behaviors suggest that the Di muscles can be activated independently relative to the myomeric musculature rather than having a single phase relationship with the myomersic muscle common to all of the observed behaviors. Expand
Mechanics of propulsion by multiple fins: kinematics of aquatic locomotion in the burrfish (Chilomycterus schoepfi)
Locomotion in tetraodontiform fishes (puffers and relatives) involves the use of multiple fins for propulsion during swimming. A variety of tertraodontiform swimming modes have been defined, but theExpand

TLDR
Both the alternating sign of the hydrodynamic angle of attack and the observed reduced frequencies suggest that unsteady effects are important in G. varius aquatic flight, especially at low speeds. Expand
A hydrodynamic analysis of fish swimming speed: wake structure and locomotor force in slow and fast labriform swimmers.
TLDR
Two hypotheses relating locomotor stability, maneuverability and the structure of the vortex wake are presented and a potential hydrodynamic trade-off between speed and maneuverability that arises as a geometric consequence of the orientation of vortex rings shed by the pectoral fins is proposed.

Wake dynamics and fluid forces of turning maneuvers in sunfish.
TLDR
This paper measures the fluid forces exerted by the left and right pectoral fins of bluegill sunfish during turning using digital particle image velocimetry (DPIV), which reflects the plasticity of the teleost pECToral fin in performing a wide range of steady and unsteady locomotor tasks. Expand
EFFECTS OF MEDIAN-FIN AMPUTATION ON FAST-START PERFORMANCE OF RAINBOW TROUT (SALMO GAIRDNERI)
TLDR
The results confirm the hydromechanical theory and lead to the conclusion that mechanically optimum lateral body profiles for faststart and for steady (cruising and sprint) performance are mutually exclusive. Expand
Function of the heterocercal tail in white sturgeon: flow visualization during steady swimming and vertical maneuvering.
TLDR
Data provide evidence that sturgeon can actively control the direction of force produced by their tail while maneuvering through the water column because the relationship between vortex jet angle and body angle is not constant. Expand

TLDR
The observed force balance indicates that DPIV can be used to measure accurately large-scale vorticity in the wake of swimming fishes and is therefore a valuable means of studying unsteady flows produced by animals moving through fluids. Expand

In relinquishing the demands of speed the seahorse has released itself from restrictions which would limit its possible range of form. Expand
