In 2013 and 2019, two separate encounters with a white shark (Carcharodon carcharias) were documented within Indonesian waters. Of particular importance was ca. 6.0 m male C. carcharias that was captured in Lombok, Indonesia in 2013, where an upper lateral tooth was retained. Using the D-loop sequences of the mitochondrial DNA (mtDNA) associated with this captured white shark, the mtDNA was compared to the available mtDNA sequences in GenBank® associated with the Northwest Pacific and Australian (i.e. Southern-Western and Eastern) C. carcharias subpopulations to determine its point of origin. Results from the mtDNA analyses suggest that the point of origin for this captured C. carcharias is from one of the Australian subpopulations. When compared to primary literature, this migration presents a northerly range extension for this species; however, since it is unclear what Australian subpopulation this shark was from it is uncertain what subpopulation this range extension applies to. Although C. carcharias presence within Indonesian waters is likely a rare occurrence, being that Indonesia represents the largest shark fin exporter in the world, the utilization of these waters and potential unsustainable exploitation poses a definitive threat to this highly migratory top predator. Therefore, further research investigating the purpose and site fidelity of C. carcharias within these waters is critical to future multijurisdictional protection of this top predator.

Forty-six individuals of Carcharodon carcharias were either recorded or sighted in Turkey's waters during a period from February 1881 to 28 September 2011. Total lengths (TLs) of the recorded great white sharks ranged from 85 cm TL to ~800 cm TL, and mass ranged between 12 kg and ~4500 kg. Three non-fatal shark attacks on boats of tuna hand-liners were also recorded. A North Aegean Sea specimen (85 cm TL; sp No. 45; Table 1) caught by a coastal trammel netter in Edremit Bay on July 6, 2011, is possibly the smallest neonate white shark from Mediterranean waters to date. Due to intensification of tuna fishing and the resulting decline or extinction of tuna stocks, C. carcharias is now apparently extinct from marmaric and bosphoric waters. Capture of 6 neonate great white sharks between 2008 and 2011, in the same period of the year (from late June to early July), in the waters of Edremit Bay (northern Aegean Sea, Turkey) suggests the possibility of a breeding ground in the region. The growing tuna farm industry offers a new possibility for encounters between humans and great white sharks off the Turkish coast.

The white shark is known to inhabit the Gulf of California, but few published records exist for the most frequent localities of captures or sightings of this protected and relatively uncommon shark in Gulf waters. We have compiled and here report 38 records of white shark captures and reliable sightings for the Gulf. Records include individuals caught as by-catch by shrimp trawlers and gill-nets, and several sightings by divers or at fishing camps with corroborating photographs or sets of jaws (teeth). The main locations of occurrence were El Golfo de Santa Clara (13 records), followed by Santa Rosalía (4), and San Pedro Mártir and San Pedro Nolasco Islands (3 each). Presence of juveniles (<300 cm total length) was highest from January to May (10 records); whereas in July and October only two juveniles were recorded. Adults were more common from December to May (8 records); whereas from June to October there were fewer (5). Human induced threats and conservation of the white shark in the Mexican Pacific are briefly discussed.
