The population there is dominated by males (about 2.2 males for every female) Oceanic whitetip sharks live up to 19 years, although it is thought that individuals may live to be much older (up to 36 years). Female oceanic whitetip sharks reach maturity between 6 and 9 years of age (depending on geographic location) and give birth to live young after a very lengthy gestation period of 10 to 12 months While this unique population of great whites spends about half of the year around these sites, they make impressive migrations far offshore near the Pacific Gyre, fondly called the white shark café as researchers think they make the trek there to feed or breed. To a lesser extent, these great whites also migrate to the Hawaiian.
White sharks in this area are from the southern-western Australian population (Australia has two populations of white shark, separated by Bass Strait). In 2018, the CSIRO provided the first abundance estimate of the adult cohort of the southern-western population Project 5 - White shark population and abundance trends. Theme: Theme 2 - Supporting management of marine biodiversity. This project will develop techniques to undertake a population assessment for white sharks in Australian waters. An assessment is necessary to understand whether the species is recovering and hence whether conservation actions. Great white sharks live in all coastal temperate waters around the world.
