On 29 January 2019, a 38-foot male Bryde’s … The Gulf of Mexico Bryde’s whale (Balaenoptera edeni) population suffered injury due to the Deepwater Horizon. The risk of vessel strikes is significant given the location of commercial shipping lanes, the whale’s swimming behavior, and the low ability of ships to change course quickly to avoid a whale. Bryde’s Whale According to NOAA, the Bryde’s whale is “perhaps the only baleen whale that regular inhabits the Gulf of Mexico,” but researchers will tell you they are still a pretty rare sight. Commercial fishing with longline and trap gear also overlaps to a limited degree with Bryde’s whale habitat. However, given the uncertainty about their existence in the southern Gulf of Mexico (i.e., Mexican and Cuban waters), the team of scientists that conducted the ESA status review believe that there are likely fewer than 100 individual Gulf of Mexico Bryde’s whales, with 50 or fewer being mature individuals. Limited data suggests that Bryde’s whales spend the most of their time within about 50 feet of the water’s surface. The northern Gulf of Mexico experiences a high amount of ship traffic where several commercial shipping lanes cross through Bryde’s whale habitat. The head of a Gulf of Mexico Bryde's whale makes up about one quarter of its entire body length. B. brydei occurs in the Atlantic, Pacific, and Indian Oceans between the 40th parallels of latitude, preferring highly productive, tropical, subtropical, and warm, temperate waters of 16–22 °C (61–72 °F). Based on the Gulf of Mexico Bryde’s whale’s small population (likely fewer than 100 individuals), its life history characteristics, its extremely limited distribution, and its vulnerability to existing threats, NMFS has determined that the Gulf of Mexico Bryde’s whale is in danger of extinction throughout all of its range. Genetic analyses have determined that the Gulf of Mexico stock is distinct from Bryde’s whale stocks in other parts of the world, and it has a very low level of genetic diversity. (NOAA).
