An upside down dead horse drifting in water attracting a shark. What? Wow, where to start!
This video blew me, because it is so out of sync with the usual YouTube videos and has fantastic archive footage of the first film shot under water: an upside down dead horse attracting a shark.
The connection of the three chapters of the video did not really add up for me, but since each chapter has its unique visual style and interesting content, I was happy to ignore it and go for the deep dive into the world of Nautiluses.
