Understanding of juvenile life stages of large pelagic predators such as the white shark Carcharodon carcharias remains limited. We tracked 6 juvenile white sharks (147 to 250 cm total length) in the eastern Pacific using pop-up satellite archival tags for a total of 534 d, demonstrating that the nursery region of white sharks includes waters of southern California, USA, and Baja Cali- fornia, Mexico. Young-of-the-year sharks remained south of Point Conception whereas one 3 yr old shark moved… 

Contrasts in the movements and habitat use of juvenile and adult white sharks (Carcharodon carcharias) at Guadalupe Island, Mexico

The data collected in this study suggest that white shark juveniles arrive to GI from nursery grounds on the mainland after they have reached at least 180 cm TL; then, they remained around the island for several months, potentially taking advantage of the diversity of prey.

Evidence of diverse movement strategies and habitat use by white sharks, Carcharodon carcharias, off southern Australia

It is highlighted that the southern-western Australian population of white sharks use off-shelf habitat to a greater extent than previously identified.

Large-scale tropical movements and diving behavior of white sharks Carcharodon carcharias tagged off New Zealand

Results from the first study in New Zealand waters using satellite tags to study sharks show that some of these movements could be part of a regular foraging migration where white sharks visit humpback whale wintering grounds to feed on carcasses and prey on newborn calves.

Movements of the white shark Carcharodon carcharias in the North Atlantic Ocean

It is found that white sharks are more broadly distributed, both horizontally and vertically, throughout the North Atlantic than previously understood, exhibiting an ontogenetic shift from near-coastal, shelf-oriented habitat to pelagic habitat with frequent excursions to mesopelagic depths.

Migration and habitat of white sharks (Carcharodon carcharias) in the eastern Pacific Ocean

Satellite telemetry studies of 20 adult and sub-adult white sharks in the eastern North Pacific during 1999–2005 revealed long distance seasonal migrations from the coast of California to an offshore focal area 2,500 km west of the Baja Peninsula, as well as the Hawaii Islands.

Broad-scale movements of juvenile white sharks Carcharodon carcharias in eastern Australia from acoustic and satellite telemetry

Long-term monitoring of acoustic-tagged sharks via data sharing through collaborative national and international receiver arrays offers future pro mise to examine movements over periods relevant to ontogenetic changes and at scales providing context to interannual variability.

Three-Dimensional Movements and Habitat Selection of Young White Sharks (Carcharodon carcharias) Across a Temperate Continental Shelf Ecosystem

As highly mobile predators with extensive home ranges, some shark species often utilize a continuum of habitats across the continental shelf ranging from the surf zone to the open ocean. For many

New insights into the trophic ecology of young white sharks (Carcharodon carcharias) in waters off the Baja California Peninsula, Mexico

This study provides relevant information regarding young white shark feeding preferences, reinforces the importance of coastal areas as critical habitat for the development and the successful foraging of this species, and also provides indirect insights on the feeding habits of the adult female of white sharks.

First insights into the movements of young-of-the-year white sharks (Carcharodon carcharias) in the western North Atlantic Ocean

Satellite and acoustic tags were deployed on ten young-of-the-year (YOY) white sharks off Long Island, New York, supporting the notion that the region is a nursery area and assessing the potential impacts of anthropogenic impacts on the western North Atlantic white shark population.

Movements and distribution of juvenile common thresher sharks Alopias vulpinus in Pacific coast waters of the USA and Mexico

: The common thresher shark Alopias vulpinus constitutes an important commercial fishery on the Pacific coasts of both the USA and Mexico. However, little is known about the juvenile phase of this



Insights into Young of the Year White Shark, Carcharodon carcharias, Behavior in the Southern California Bight

A young of the year female white shark, Carcharodon carcharias, was tagged with a pop-up satellite archival tag off Southern California in early June of 2000. The tag was recovered after 28 days, and

Preliminary observations on the biology of the White Shark, Carcharodon carcharias, in South Australian waters

The seasonal and geographic distribution of three size categories of white sharks, Carcharodon carcharias ( 450 cm), is described for South Australian waters and sex ratios highly favoured females, suggesting some sexual segregation.

The hunting strategy of white sharks (Carcharodon carcharias) near a seal colony

The behavior and movements of the sharks were consistent with a hunting strategy, in which individuals search for prey independently but, at the same time, remain close enough to each other to “sense” and exploit a kill by any one of them by joining in on the kill to feed.

Northerly Distribution of White Sharks, Carcharodon carcharias, in the Eastern Pacific and Relation to ENSO Events

Twenty-nine verified records of white sharks, Carcharodon carcharias, from British Columbia and Alaska waters (1961–2004) are presented. Record locations ranged from lat. 48°48ʹN to lat. 60°17ʹN,

Movements and Swimming Behavior of Three Species of Sharks in La Jolla Canyon, California

We tracked six individuals of three shark species, the shortfin mako, Isurus oxyrinchus, great white, Carcharodon carcharias, and blue, Prionace glauca, near the submarine canyon off La Jolla,

Predation by White Sharks Carcharodon carcharias (Chondrichthyes: Lamnidae) Upon Chelonians, with New Records from the Mediterranean Sea and a First Record of the Ocean Sunfish Mola mola (Osteichthyes: Molidae) as Stomach Contents

The white shark may be the chief marine predator of adult chelonians in the Mediterranean Sea, albeit the impact of this predation upon turtle populations is nominal compared to other sources of mortality.

Movements, behavior, and habitat selection of bigeye tuna (Thunnus obesus) in the eastern equatorial Pacific, ascertained through archival tags

Ninety-six bigeye tuna (88– 134 cm fork length) were caught and released with implanted archival (electronic data storage) tags near fish-aggregating devices (FADs) in the equatorial eastern Pacific

Movement patterns, depth preferences, and stomach temperatures of free-swimming juvenile mako sharks, Isurus oxyrinchus, in the Southern California Bight

Stomach content analyses of four makos captured at the end of tracking verified the occurrence of feeding events as indicated by changes in stomach temperature, and body size was positively correlated with both maximum and average stomach temperature.

Horizontal and vertical movements of the shortfin mako shark, Isurus oxyrinchus, in the southern California bight.

Acoustic telemetry was used to identify short-term horizontal and vertical movements of three shortfin mako sharks in the southern California bight during the summer of 1989, and vertical and horizontal movements did not indicate any diel activity pattern associated with distance to the shore or nearby islands or with bottom topography.

Movements of blue sharks (Prionace glauca) in depth and course

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.
