SUMMARY Crocodilians, including the alligator (Alligator mississippiensis), perform a spinning maneuver to subdue and dismember prey. The spinning maneuver, which is referred to as the `death roll', involves rapid rotation about the longitudinal axis of the body. High-speed videos were taken of juvenile alligators (mean length=0.29 m) performing death rolls in water after biting onto a pliable target. Spinning was initiated after the fore- and hindlimbs were appressed against the body and the… 
Swimming Turned on Its Head: Stability and Maneuverability of the Shrimpfish (Aeoliscus punctulatus)
TLDR
Modification of the design of the body and position of the fins allows the shrimpfish to effectively swim in the head-down orientation.
Come on baby, let's do the twist: the kinematics of killing in loggerhead shrikes
TLDR
High-speed videography observed that upon seizing prey with their beaks, shrikes performed rapid axial head-rolling movements that may be sufficient to cause pathological damage to the cervical vertebrae and spinal cord.
Scaling the Feeding Mechanism of Captive Alligator mississippiensis from Hatchling to Juvenile
TLDR
Investigation of the scaling of the feeding mechanism and its performance from hatchling to juvenile size classes in A. mississippiensis indicated that many linear, angular and timing kinematic variables scale allometrically with cranium length; whereas maximum gape velocity and duration of feeding bout do not scale withCranium length and remain constant between these size classes.
Kinematics of swimming of the manta ray: three-dimensional analysis of open-water maneuverability
TLDR
Underwater stereovideography detailing the three-dimensional maneuvering performance of the manta ray in its natural environment shows that its turning maneuvers fall within the range of those exhibited by swimmers with rigid bodies.
Hydrodynamic properties of fin whale flippers predict maximum rolling performance
TLDR
A simple hydrodynamic model is constructed to predict the longitudinal-axis roll performance of fin whales, and its predictions are tested against kinematic data recorded by on-board movement sensors from 27 free-swimming fin whales.
Feeding Mechanics in Spinosaurid Theropods and Extant Crocodilians
TLDR
Biomechanical data support known feeding ecology for both African slender-snouted crocodile and alligator, and suggest that the spinosaurs were not obligate piscivores with diet being determined by individual animal size.
Recruitment of the diaphragmaticus, ischiopubis and other respiratory muscles to control pitch and roll in the American alligator (Alligator mississippiensis)
TLDR
Electromyography on juvenile American alligators raised the possibility that the locomotor function arose when Crocodylomorpha assumed a semi-aquatic existence and that the musculoskeletal complex was secondarily recruited to supplement ventilation.
Surveying death roll behavior across Crocodylia
TLDR
The patterns of death roll behavior observed suggest that this behaviour is not novel to any one crocodylian clade, morphotype, or dietary niche, and the prevalence of death rolling behaviour across Crocodylia in response to perceived threats indicates that it is not solely, or maybe even primarily, a feeding behaviour, but is also utilised during inter- and intra-specific conflict as a means to escape or injure an opponent.
Elongation of the body in eels.
TLDR
The diversity of axial elongation is described as well as how characters such as head length, branchial-arch length, and shape of the pectoral fins correlate with vertebral number to possibly facilitate changes in absolute diameter of the body.

Dynamics of the aerial maneuvers of spinner dolphins
TLDR
A mathematical model was developed that demonstrates that angular momentum to induce the spin was generated underwater, prior to the leap, and indicates that the high rotation rates and orientation of the dolphin's body during re-entry into the water could produce enough force to hydrodynamically dislodge unwanted remoras.

The kinematics and performance of the escape responses of the knifefish Xenomystus nigri, a fish specialized for low-speed, undulatory median-fin propulsion, were recorded by means of high-speed
Hydrodynamic design of the humpback whale flipper
TLDR
The morphology and placement of leading edge tubercles suggest that they function as enhanced lift devices to control flow over the flipper and maintain lift at high angles of attack in the humpback whale.

Maneuverability by the sea lion Zalophus californianus: turning performance of an unstable body design
TLDR
Comparison with other marine mammals indicates that Zalophus has a morphology that enhances instability, thus providing enhanced turning performance, necessary for sea lions to forage after highly elusive prey in structurally complex environments.
Aquatic turning performance of painted turtles (Chrysemys picta) and functional consequences of a rigid body design
TLDR
The maneuverability of turtles is similar to that recorded previously for rigidbodied boxfish, however, several morphological features of turtles appear to increase agility relative to the body design of boxfish.
The ontogeny of bite-force performance in American alligator (Alligator mississippiensis)
TLDR
The bite-force values for adult A. mississippiensis are the highest measured for any living animal and represent the first measures for a large crocodilian, and provide the first documentation of how bite force changes during ontogeny in a reptile.
TURNING MANEUVERS IN STELLER SEA LIONS (EUMATOPIAS JUBATUS)
TLDR
The relative maneuverability based on velocity and length specific minimum turning radius is comparable to other otariids, superior to cetaceans but inferior to many fish.
Rotational feeding in caecilians: putting a spin on the evolution of cranial design
TLDR
It is demonstrated that long-axis body rotations are used independent of prey size by these two species of caeciliid caecilians when feeding underground, and that individuals are capable of generating a substantial spinning force, which is greater than their bite force.
