Occurrence 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 کاملMigration 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 کاملEffects of provisioning ecotourism activity on the behaviour of white sharks Carcharodon carcharias
Ecotourism operations which provide food to large predators have the potential to negatively affect their target species, by conditioning them to associate humans with food, or by generally altering their behavioural patterns. This latter effect could have potentially detrimental consequences for the ecosystem inhabited by the predator, because any behavioural changes could affect the species w...
متن کاملSeasonal Distribution and Historic Trends in Abundance of White Sharks, Carcharodon carcharias, in the Western North Atlantic Ocean
Despite recent advances in field research on white sharks (Carcharodon carcharias) in several regions around the world, opportunistic capture and sighting records remain the primary source of information on this species in the northwest Atlantic Ocean (NWA). Previous studies using limited datasets have suggested a precipitous decline in the abundance of white sharks from this region, but consid...
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...
