Occurred on June 29, 2021 / Naples, Florida, USA
Info from Licensor: "This video was taken mid-morning from Naples Pier in Florida. As I was exiting the boardwalk, I noticed a giant black cloud headed directly toward the shore where people were swimming and enjoying the weather. I followed the cloud and when the animals got closer I noticed the group of manatees trying to get to the shore for mating. The video shows the manatees as they are trying to get to shore but couldn't because there were so many beachgoers that day who were also very interested in what was happening."
