wanna know something about dolphin?

The story of the legend itself is told in a Brazilian film called THE DOLPHIN (1987) which is in Portugese with English subtitles. In the film, a pink river dolphin becomes a man on nights of the full moon. He comes onto land and makes love to a woman, making her pregnant, then abandoning her when he returns to his true form in the black river water. Their male cross-breed offspring has an Oedipal desire for his human mother causing him to pursue and haunt her.

An interesting film despite its low-budget look, there is one scene which the man is on top of the woman when his legs suddenly turn to a dolphin tail and he splashes off into the river. We never see him as a merman, but the fact that he is one is of course suggested.
