Gulf of Mexico Bryde's (pronounced "broodus") whales are members of the baleen whale family and a subspecies of the Bryde’s whale. Limited data suggests that Bryde’s whales spend the most of their time within about 50 feet of the water’s surface. The plastic piece had sliced through part of the whale’s stomach, which likely contributed to its death. Collisions with vessels are a major cause of injury and death for whales. The Gulf of Mexico Bryde's whales are reproductively isolated and on a unique evolutionary trajectory. Accidental vessel strikes can injure or kill Gulf of Mexico Bryde’s whales. However, in order to further protect the Gulf of Mexico subspecies and aid in its recovery, in 2016 NOAA Fisheries proposed a rule to list it as endangered under the Endangered Species Act. Northern Gulf of Mexico (map adapted from NMFS core distribution area as of June 2019). Fewer than 50 mature animals remain, surviving only in a narrow slice of the northeastern Gulf called De Soto Canyon. These whales vary in coloration from rusty-brown, dark gray, or tan. NOAA Fisheries continually conducts research to learn more about the biology, behavior, and ecology of Gulf of Mexico Bryde’s whales to better inform management and policy decisions. Expected outcomes include an improved understanding of population status, identification of habitat features and characteristics (including critical habitat primary constituent elements), and a better understanding of the risk of exposure to human activities in the Gulf. For the past 25 years, Bryde’s whales in U.S. waters of the Gulf of Mexico have been consistently located in the northeastern Gulf of Mexico along the continental shelf break between 100m and 400m depth. Worldwide, Bryde’s whales have 40 to 70 throat grooves on their underside that expand while feeding and 250 to 410 short baleen plates on each side of their mouths that act as strainers as they feed. The Marine Mammal Commission is working with NMFS and other partners in the Gulf of Mexico to expand research and monitoring efforts for all marine mammals. There is a low level of genetic divergence and they are not mixing with other Bryde’s whales. Energy exploration, development and production, NMFS subsequently initiated a status review of Bryde’s whales under the ESA, which was finalized in December 2016. Commercial fishing with longline and trap gear also overlaps to a limited degree with Bryde’s whale habitat.
