Below is apparently video taken of a beach in the Bahamas where the water was sucked away by Hurricane Irma. The storm has been responsible for a number of deaths throughout the Caribbean and has laid waste to various islands including Barbuda where it was believed around 95 percent of the structures on the Island were destroyed.
Anyways, I’m not marine biologist and have no idea how this happened or how genuine the video is.
If it’s real, it’s a pretty remarkable phenomenon of nature.
