Migration and habitat of white sharks (Carcharodon carcharias) in the eastern Pacific Ocean
Satellite telemetry studies of 20 adult and subadult white sharks (360–530 cm estimated total length (TL)) 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. Three tags were recovered allowing detailed behavioral analyses, including one...
متن کاملOccurrence of White Sharks (Carcharodon carcharias) in Hawaiian Waters
White sharks (Carcharodon carcharias) have been known in Hawaii (∼158W, 22N) since the time of ancient Hawaiians. We compiled sightings and records from 1926 to the present (4 females, 2 males, and 8 unknown sex; 3.3–4.5m total length) and compared them with satellite tracking records (7 females, 9 males, and 6 unknown; 3.7–5.3m total length). White sharks have been sighted in Hawaii throughout...
متن کاملContaminants in Muscle and Liver tissue of Juvenile White Sharks, Carcharodon carcharias, from the Southern California Bight
The Southern California Bight (SCB) is thought to be a nursery ground for the White Shark (Carcharodon carcharias) in the eastern north Pacific. Because of their proximity to highly urbanized coastline in the SCB, juvenile White Sharks are potentially exposed to relatively high levels of trace elements, heavy metals, and organochlorines. To assess potential exposure levels, concentrations of 17...
متن کاملResidency, Habitat Use and Sexual Segregation of White Sharks, Carcharodon carcharias in False Bay, South Africa
White sharks (Carcharodon carcharias) are threatened apex predators and identification of their critical habitats and how these are used are essential to ensuring improved local and ultimately global white shark protection. In this study we investigated habitat use by white sharks in False Bay, South Africa, using acoustic telemetry. 56 sharks (39 female, 17 male), ranging in size from 1.7-5 m ...
متن کاملEvidence of Maternal Offloading of Organic Contaminants in White Sharks (Carcharodon carcharias)
Organic contaminants were measured in young of the year (YOY) white sharks (Carcharodon carcharias) incidentally caught in southern California between 2005 and 2012 (n = 20) and were found to be unexpectedly high considering the young age and dietary preferences of young white sharks, suggesting these levels may be due to exposure in utero. To assess the potential contributions of dietary expos...
