The world's second largest fish, the basking shark (Cetorhinus maximus), is broadly distributed in boreal to warm temperate latitudes of the Atlantic and Pacific oceans from shallow coastal waters to the open ocean. Previous satellite archival tagging in the North Atlantic has shown that basking sharks move seasonally, are often associated with productive frontal zones, and may make occasional dives to mesopelagic depths. However, basking sharks are thought to be restricted to temperate… Expand
Basking Shark (Cetorhinus maximus) Movements in the Eastern North Pacific Determined Using Satellite Telemetry
To fill data gaps on movements, behaviors and habitat use both near- and offshore, two programs were initiated to deploy satellite tags on basking sharks. Basking sharks are large filter feedingExpand
Movements, Habitat Use, and Diving Behavior of Shortfin Mako in the Atlantic Ocean
The shortfin mako is one of the most important shark species caught in Atlantic Ocean pelagic fisheries. Given increasing concerns for the stock status of the species, the present study was designedExpand
Horizontal and Vertical Movement Patterns and Habitat Use of Juvenile Porbeagles (Lamna nasus) in the Western North Atlantic
The porbeagle (Lamna nasus) is a large, highly migratory endothermic shark broadly distributed in the higher latitudes of the Atlantic, South Pacific, and Indian Oceans. In the North Atlantic, theExpand
Horizontal movement of ocean sunfish, Mola mola, in the northwest Atlantic
Ocean sunfish tagged in the Gulf of Maine and southern New England left those areas in the late summer and early autumn and moved south along the continental shelf break and fish moved farther offshore in 2007 when the Gulf Stream was deflected from the shelf break. Expand
Basking sharks in the northeast Atlantic: spatio-temporal trends from sightings in UK waters
Basking sharks Cetorhinus maximus have undergone widespread historic exploita- tion in the northeast Atlantic and are of conservation concern. A greater knowledge of their spatial and temporalExpand
Complex Movements, Philopatry and Expanded Depth Range of a Severely Threatened Pelagic Shark, the Oceanic Whitetip (Carcharhinus longimanus) in the Western North Atlantic
The sharks tracked appear to be most vulnerable to pelagic fishing gear deployed from 0–125 m depths, which they may encounter from June to October after leaving the protected waters of The Bahamas EEZ. Expand
Leatherback Turtle Movements, Dive Behavior, and Habitat Characteristics in Ecoregions of the Northwest Atlantic Ocean
High-use habitat for leatherbacks in this study occurred in coastal waters of the North American eastern seaboard and eastern Caribbean, putting turtles at heightened risk from land- and ocean-based human activity. Expand
Migration and diving behavior of Centrophorus squamosus in the NE Atlantic. Combining electronic tagging and Argo hydrography to infer deep ocean trajectories
Abstract A total of nine leafscale gulper sharks Centrophorus squamosus ( Bonnaterre, 1788 ), were tagged with pop-up, satellite, archival, transmitting tags (PSAT) in the Marine Protected Area (MPA)Expand
Horizontal Movements, Migration Patterns, and Population Structure of Whale Sharks in the Gulf of Mexico and Northwestern Caribbean Sea
The broad movements of whale sharks across multiple political boundaries corroborates genetics data supporting gene flow between geographically distinct areas and underscores the need for management and conservation strategies for this species on a global scale. Expand
Basking sharks and oceanographic fronts: quantifying associations in the north‐east Atlantic
Temporally-matched oceanographic metrics indicate that sharks demonstrate a preference for productive regions, and associate with contemporaneous thermal and chl-a fronts more frequently than could be expected at random, highlighting the importance of cross-frontal temperature change and persistence.

Transatlantic migration and deep mid-ocean diving by basking shark
This result provides the first evidence for a link between European and American populations and indicates that basking sharks make use of deep-water habitats beyond the shelf edge. Expand
Archival tagging of a basking shark, Cetorhinus maximus, in the western North Atlantic
A 6·1-m long female basking shark (Cetorhinus maximus) was tagged 73 km east of Nantucket Island, Massachusetts on 27 September 2001 with a pop-up archival transmitting tag. The tag detachedExpand
Seasonal movements and behaviour of basking sharks from archival tagging: no evidence of winter hibernation
Habitat selection processes in highly migratory animals such as sharks and whales are important to understand because they influence patterns of distribution, availability and therefore catch rates.Expand
Distribution, seasonal abundance and bycatch of basking sharks (Cetorhinus maximus) in New Zealand, with observations on their winter habitat
Support is provided for the hypothesis that basking sharks over-winter in deep water on the continental slope, because hibernating sharks are unlikely to hover in midwater in winter. Expand
Sieving a living: a review of the biology, ecology and conservation status of the plankton-feeding basking shark Cetorhinus maximus.

This chapter reviews the taxonomy, distribution and habitat, bionomics and life history, behaviour, population structure, exploitation, management and conservation status of the basking shark and reveals that whilst important behavioural and ecological information has been gained, there are still considerable gaps in knowledge.

Low worldwide genetic diversity in the basking shark (Cetorhinus maximus)
Evidence for a bottleneck event within the Holocene is provided, an effective population size that is low for a globally distributed species is estimated, and the implications are discussed. Expand
Horizontal movements of bigeye tuna (Thunnus obesus) near Hawaii determined by Kalman filter analysis of archival tagging data
Geolocation data were recovered from archival tags applied to bigeye tuna near Hawaii. A state-space Kalman filter statistical model was used to estimate geolocation errors, movement parameters, andExpand
Bullhead, mackerel and carpet sharks (Heterodontiformes, Lamniformes and Orectolobiformes)
The present volume reviews all 15 families, 25 genera and 57 species of living bullhead, mackerel and carpet sharks, including certain well-established but currently undescribed species mainly from Australia. Expand
Threshold foraging behaviour of basking sharks on zooplankton: life on an energetic knife-edge?

It is shown from theoretical calculations and behavioural studies on individual and group-feeding sharks in the English Channel that basking sharks have a theoretical threshold prey density and an observed foraging threshold of between 0.55 and 0.74 g m−3, which implies that this species may not be reliant upon the ‘migration–hibernation’ energy conservation strategy it is purported to exhibit when seasonal zooplankton abundance decreases below 1.36 gm−3.
