Bottlenose dolphins have appeared in novels. In "The Hitchhiker's Guide to the Galaxy" and one of its sequels, "So Long, and Thanks For All the Fish", the dolphins try to warn humans of Earth's impending destruction, but their behavior was misinterpreted as playful acrobatics. Bottlenose dolphins are central to David Brin's series of Uplift Universe novels, particularly "Startide Rising", where they are one of the four Earth species (along with chimpanzees, gorillas, and dogs) to have been 'uplifted' to sentience. Bottlenose dolphins are primary characters in Anne McCaffrey's "Dragonriders of Pern" series, especially "The Dolphins of Pern". Bottlenose dolphins have been mentioned in various "Star Trek" novels and other materials as serving as navigation specialists onboard various Federation starships.
