An accomplished musician, who plays her flute to the whales, has been captured on video experiencing a close encounter with the mammals in the Californian ocean.
A YouTube video shows Chilean-born flautist Viviana Guzmán paddle-boarding with friends at Half Moon Bay, while playing the flute at the same time.
Moments later, a huge humpback whale pops out of the water right beside the woman, who calls herself the 'Flute Queen', almost knocking her off her board.
"Oh, my God," she shouts with a fright as the massive sea animal leaps up into the air, just inches from her board.
A friend of Guzmán captures the moment from a different angle, which is also shown in the clip.
The video package also shows a magical moment where Guzmán is kneeling on her board, playing the flute.
Tthe sound attracts a whale who swims toward her the like the Pied Piper.
"She came to you!" her excited friend can be heard shouting with glee in the background.
Ms Guzmán has performed her music in more than 125 countries and has also been nominated for a Grammy Award.
A graduate of the Juilliard School, she has performed in Carnegie Hall five times and has played as soloist with orchestras in Russia, Chile, Vermont, New York, Wisconsin, California, Texas, Montana.
