Abstract. Understanding the foraging behavior and spatial distribution of top predators is crucial to gaining a complete understanding of communities. However, studies of top predators are often logistically difficult and it is important to develop appropriate methods for identifying factors influencing their spatial distribution. Sharks are top predators in many marine communities, yet no studies have quantified the habitat use of large predatory sharks or determined the factors that might… 
Validation of a randomization procedure to assess animal habitat preferences: microhabitat use of tiger sharks in a seagrass ecosystem.
TLDR
The randomization procedures presented here are applicable to many field studies that use tracking by allowing researchers both to determine overall habitat preferences and to identify differences in habitat use between groups within their sample.
Regional variation in tiger shark (Galeocerdo cuvier) abundance and habitat use
TLDR
The results suggest that large predator abundance and habitat use may vary over relatively small spatial scales and that such variation may be useful for elucidating their ecological interests.
Habitat use and group size of pied cormorants (Phalacrocorax varius) in a seagrass ecosystem: possible effects of food abundance and predation risk
TLDR
This study provides the first evidence that marine habitat selection by birds may be influenced by such a trade-off, and provides further evidence that tiger sharks are important in determining habitat use of their prey and mediating indirect interactions within Shark Bay.
FOOD AVAILABILITY AND TIGER SHARK PREDATION RISK INFLUENCE BOTTLENOSE DOLPHIN HABITAT USE
TLDR
The results suggest that foraging dolphin distributions reflect a trade-off between predation risk and food availability, and that it is important to consider the community context in studies of habitat use.
Diet and trophic ecology of the tiger shark (Galeocerdo cuvier) from South African waters
TLDR
This study presents the longest time-series and most detailed analysis of stomach content data for G. cuvier worldwide to improve the accuracy of regional food web modelling and enable a better understanding of the ecological impacts related to changes in the abundance of this predator.
Feeding habits of the tiger shark, Galeocerdo cuvier, in the northwest Atlantic Ocean and Gulf of Mexico
TLDR
Diet was assessed from 169 tiger sharks by life stage, area, and environmental factors, and fifteen prey groups were identified, with teleosts, molluscs, birds, cephalopods, and reptiles being the predominant prey categories.
Vertical Movement Patterns and Ontogenetic Niche Expansion in the Tiger Shark, Galeocerdo cuvier
TLDR
A clear ontogenetic expansion in the vertical range of tiger shark habitat was observed, with generalized linear models estimating a ~4-fold increase in maximum diving depth from 150- to 300-cm size-classes.
Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales
TLDR
The results suggest that predation risk and prey availability influence dolphin habitat use at multiple spatial scales, but intrinsic habitat risk, and not just predator encounter rate, is important in shaping dolphin space use decisions.
Influence of teleost abundance on the distribution and abundance of sharks in Florida Bay, USA
TLDR
Although there does not appear to be a strong match between the abundance of teleosts and sharks at small spatial scales, regional shark abundance is likely driven, at least partially, by the availability of prey.
Residency and movement patterns of an apex predatory shark (Galeocerdo cuvier) at the Galapagos Marine Reserve
TLDR
The spatial patterns of residency and site fidelity of tiger sharks suggest that the presence of a predictable source of prey and suitable habitats might reduce the spatial extent of this large shark that is highly migratory in other parts of its range.

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.
Selective foraging behaviour of basking sharks on zooplankton in a small-scale front
The basking shark Cetorhinus maximus is the second largest fish species, attaining lengths of up to 11 m. During summer months in temperate coastal waters circumglobally, these sharks filter-feed on
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.
Biology of Tiger Sharks (Galeocerdo cuvier) caught by the Queensland Shark Meshing Program off Townsville, Australia
TLDR
There was no apparent decrease in the population size of G. cuvier in the Townsville area as a result of the long-term catching of sharks by the protective meshing programme, and the sex ratio of juveniles and adults favoured females, with few adult males being caught.
SHARK ATTACKS ON BOTTLENOSE DOLPHINS (TURSIOPS ADUNCUS) IN SHARK BAY, WESTERN AUSTRALIA: ATTACK RATE, BITE SCAR FREQUENCIES, AND ATTACK SEASONALITY
TLDR
The frequency of shark-inflicted scars and the shark attack rate on bottlenose dolphins in Shark Bay, Western Australia suggest that Shark Bay dolphins face a greater risk of predation than bottlenOSE dolphins in other locations.
RELATIONSHIPS OF THE BLUE SHARK, PRIONACE GLAUCA, AND ITS PREY SPECIES NEAR SANTA CATALINA ISLAND, CALIFORNIA 1
TLDR
Small fishes and cephalopods associated with both pelagic and inshore habitats composed the major prey for the blue shark, Prionace glauca, near Santa Catalina Island, Calif, and field observations of feeding behavior indicate that predatory modes vary in response to prey behavior.

This paper presents information on the movements of white sharks, Carcharodon carcharias, at the South Farallon Islands (SFI), central California. Acoustic telemetry techniques provided preliminary
Assessing habitat selection when availability changes
We present a method of comparing data on habitat use and availability that allows availability to differ among observations. This rnethod is applicable when habitats change over time and when animals
Movements of blue sharks (Prionace glauca) in depth and course
TLDR
Acoustic telemetry was used to follow 22 blue sharks,Prionace glauca (Linnaeus), over the continental shelf and slope in the region between George's Bank and Cape Hatteras between 1979 and 1986, finding that they may orient to the earth's magnetic field, or to the ocean's electric fields, allowing them to swim on a constant heading in the absence of celestial cues.
