The Love Life of the Octopus (1965, French: Amours de la pieuvre) is a film on octopi by Jean Painlevé, who is also the narrator. The music is by Pierre Henry.

Last year, or two years ago, I saw Microcosmos and for a while I was very much into the love lives of animals[1].

The Love Life of the Octopus has also a scene of lovemaking of octopi.
