Bryde's whale (/ ˈ b r ʊ d ə z / BRUU-dəz), or the Bryde's whale complex, putatively comprises two species of rorqual and maybe three. The greatest threat to the whales in the Hauraki Gulf is ship-strike mortality (Behrens 2009) and the species is listed as critically endangered in NZ waters (Baker et al. […] 3. Scientists hope the skeleton will provide more information to aid research into Bryde's whale populations existing today as well as the geological conditions at the time. This project will gather and share information on how this small, resident population of whales relies on the northeastern Gulf of Mexico food web and will provide critical information to managers for recovery and restoration activities. Adult female Bryde’s whales average about 44 feet long and males average 42 feet, about the length of a school bus. In New Zealand, they are seldom seen further south than the North Island. Acknowledgements Status Some populations were seriously depleted as a result of historical whaling practices. Estimated Current Population: 40-80,000 animals (2000).

The recent identification of Omuras whales (Balaenoptera omurai) a whale similar to the Bryde’s whale, in the north west of Madagascar (Cerchio et al., 2015), casts some uncertainty on the distribution of Bryde’s whales in Malagasy waters. The research team conducted an analysis of Bryde’s whale populations in the Indian and Pacific Oceans to fill in these knowledge gaps by examining new genetic samples from 56 individual whales from the waters of Oman, Maldives, and Bangladesh.
