Sure, most of this Animal Planet special is just CG with actors, but according to Discovery, it’s “based on some real events and scientific theory.” In other words, it “unravels mysterious underwater sound recordings, dives deep into the aquatic ape theory and questions if mermaids are related to people.” Best of all, we’ve get the entire 1-hour, 28-minute video for your viewing enjoyment after the break.

The film blends real-life events and phenomena with the story of two scientists who testify they found the remains of a never-before-identified sea creature. Spectacular CGI animates a world where mermaids really do swim below the water’s surface, cooperatively hunt with dolphins and may continue to survive in an intricate society where they stay hidden in fear of their Earth-bound relatives.
