The Okavango River empties into desert; wildlife such as fish eagles, Nile crocodiles, lions and sitatunga antelope.

Emmy award-winning filmmaker and marine biologist Rick Rosenthal teams up with science fiction writer Chris Carter on an investigative journey to explore evidence of intelligent life, not in space, but in the sea – specifically, manta rays. Might these alien-looking animals be trying to make contact with us? There are intriguing clues.

Marine biologist and cameraman Rick Rosenthal has been filming in the ocean for decades, but one spectacle has eluded him and other filmmakers, until now.

Rosenthal captures the often bizarre and still unchartered life forms that make up the largest animal migration on the planet.
