Sharks as a group have a long history as highly successful predatory fishes. Although, the number of recent studies on their diet, feeding behavior, feeding mechanism, and mechanics have increased, many areas still require additional investigation. Dietary studies of sharks are generally more abundant than those on feeding activity patterns, and most of the studies are confined to relatively few species, many being carcharhiniform sharks. These studies reveal that sharks are generally… 
Mechanics of Suction Generation During Feeding in Little Skates
TLDR
Prey capture and manipulation behaviors in skates and sharks are compared and contrasted with the white-spotted bamboo shark, indicating that skates are capable of generating stronger suction than that used to capture prey.
The integration of locomotion and prey capture in vertebrates: Morphology, behavior, and performance.

TLDR
Several variables of locomotor performance related to prey capture are discussed, new data on the relationship between locomotor and feeding morphology in fishes are presented, and the evolution of prey capture in cichlid fishes is discussed, to outline some future directions for research.
Patterns of growth and the effects of scale on the feeding kinematics of the nurse shark (Ginglymostoma cirratum)
TLDR
Examination of scale effects on prey capture kinematics in the nurse shark Ginglymostoma cirratum shows a pattern of scaling across several taxa of aquatic vertebrates consistent with a second model of musculoskeletal scaling, although it does not necessarily apply within each taxon.
Field-Based Feeding Performance and Kinematics of Bull Sharks, Carcharhinus leucas (Carcharhiniformes: Carcharhinidae)
Feeding performance represents a suite of kinematic events and behaviors that achieve the ecologically relevant task of nutrient acquisition. Quantitative accounts of feeding kinematics in large wild
A Comparison of the Foraging Ecology and Bioenergetics of the Early Life-Stages of Two Sympatric Hammerhead Sharks
TLDR
Evidence is provided that juvenile hammerhead species coexist in coastal northwest Florida by feeding at separate trophic levels, and stable isotope analysis showed S. lewini had significantly higher (delta)15N values and significantly lower ( delta)13C values than S. tiburo, consistent with the difference observed in calculated trophIC level.
Food habits, selectivity, and foraging modes of the school shark Galeorhinus galeus
TLDR
The foraging ecology of the school shark Galeorhinus galeus was studied in Anegada Bay, Argentina, during the seasonal occurrence of this species in Argentinean waters from 1998 to 2001, indicating that G. galeUS is able to overcome gape limitation by mutilating prey, and that the ontogenetic diet shift was not due to a change in the ability to seize prey.
Fluid dynamics of feeding behaviour in white-spotted bamboo sharks
TLDR
The `feeding modulation hypothesis' states that rapid suction strikes are pre-programmed stereotyped events that proceed to completion once initiated regardless of sensory input, and if this hypothesis holds true, successful strikes should be indistinguishable from unsuccessful strikes owing to a lack of feedback control in specialized suction feeding fishes.
odulation of shark prey capture kinematics in response to sensory eprivation
The ability of predators to modulate prey capture in response to the size, location, and behavior of prey is critical to successful feeding on a variety of prey types. Modulating in response to
Modulation of shark prey capture kinematics in response to sensory deprivation.
Evolution and ecology of feeding in elasmobranchs.
TLDR
Prey capture in a diverse assemblage of purported suction-feeding elasmobranchs is investigated in this study and drop in water pressure measured in the mouth and at the location of the prey shows that suction inflow drops off rapidly with distance from the predator's mouth.

Capture Success and Diet of Cottid Fishes: The Role of Predator Morphology and Attack Kinematics
TLDR
The success of the simple predictions presented here provides hope that general predictions of foraging ecology may be derived from morphological patterns when the prey are treated not by their taxonomic affinities but by the functional demands they make on their pred- ators.
Effects of prey size and mobility on prey-capture kinematics in leopard sharks triakis semifasciata
  • Ferry-Graham
  • Environmental Science
    The Journal of experimental biology
  • 1998
TLDR
In leopard sharks, little effect of prey elusivity was found for kinematic variables during prey capture, but the large proportion of successful captures of the live prey suggests that they did not prove to be truly elusive prey items for the leopard shark.
Observations on the predatory behaviour of the sevengill shark Notorynchus cepedianus
TLDR
Observations on the feeding behaviour of the sevengill shark Notorynchus cepedianus over a seven-year period revealed this species to display at least four distinct foraging strategies, and four primary factors that appear to influence prey selection were prey size, availability and density, and scavenging.
Patterns of growth and the effects of scale on the feeding kinematics of the nurse shark (Ginglymostoma cirratum)
TLDR
Examination of scale effects on prey capture kinematics in the nurse shark Ginglymostoma cirratum shows a pattern of scaling across several taxa of aquatic vertebrates consistent with a second model of musculoskeletal scaling, although it does not necessarily apply within each taxon.
Ontogenetic dietary shifts and feeding behavior of the tiger shark, Galeocerdo cuvier, in Hawaiian waters
TLDR
Comparisons between the diets of tiger sharks from Hawaii and other locations indicate that ontogenetic shifts are universal in this species and that tiger sharks may be opportunistic feeders that prey heavily on abundant, easy to capture prey.
Modulation of attack behavior and its effect on feeding performance in a trophic generalist fish,
  • Németh
  • Environmental Science
    The Journal of experimental biology
  • 1997
TLDR
Data suggest that functional differences in prey anti-capture behavior, as well as the functional versatility of the predator, must be addressed in ecomorphological studies that try to correlate predator morphology with diet.
Observations on the diet and feeding habits of the epaulette shark, Hemiscyllium ocellatum (Bonnaterre), on Heron Island Reef, Great Barrier Reef, Australia
TLDR
The diet and feeding habits of the epaulette shark, Hemiscyllium ocellatum, were investigated through stomach content analysis and showed worms and crabs to be of greatest value.
Feeding Behavior in Three Species of Sharks
TLDR
A critical study of shark behavior, undertaken with planned experiments in the sharks' natural environment, conducted in the lagoon at Eniwetok Atoll, Marshall Islands, during the summers of 1959 and 1960.
Diet, feeding habits, and diel feeding chronology of the bonnethead shark, Sphyrna tiburo, in southwest Florida
TLDR
Results suggest that S. tiburo is a specialist that undergoes dietary shifts depending on season and habitat, and the shortcomings of the most commonly used approach and the limited value of considering only stomach contents weight to investigate diel feeding chronology are revealed.
Conservation and variation in the feeding mechanism of the spiny dogfish squalus acanthias
  • Wilga, Motta
  • Environmental Science

  • 1998
TLDR
The mechanism of upper jaw protrusion was found to differ between squaliform and carcharhiniform sharks, indicating that individual sharks are capable of varying head movements and motor activity among successful feeding events.
