    • NOAA Fisheries collaborates with various entities to conserve bottlenose dolphins through science, partnerships, and outreach
    • Scientists use innovative techniques for studying, protecting, and rescuing distressed bottlenose dolphins
    • 61 stocks of common bottlenose dolphins have been identified in U.S. waters, with population trends for many stocks unknown
    • Appearance of bottlenose dolphins varies from light gray to almost black on top and light gray to almost white on their belly
    • Bottlenose dolphins may travel alone or in groups, characterized by persistent movement in a consistent direction
    • They thrive in diverse environments and feed on fish, squid, and crustaceans using various hunting techniques
    • Bottlenose dolphins are found in temperate and tropical waters worldwide, including the U.S. West Coast, East Coast, Gulf of Mexico, and the Caribbean
    • They can live at least 40 years, with females reaching sexual maturity earlier and giving birth every 3 to 6 years
    • Main threats to bottlenose dolphins include entanglement in fishing gear, habitat destruction, and biotoxins from harmful algal blooms
    • Entanglement in commercial and recreational fishing gear poses a significant threat to bottlenose dolphins
    • Habitat destruction and degradation, including oil spills and chemical contamination, affect the immune systems and reproductive success of dolphins
    • Several unusual mortality events have occurred due to harmful algal blooms, such as red tide, impacting bottlenose dolphins
