A family walking along a beach in Wales recently spotted a log laden with goose barnacles, which are considered a delicacy in Spain and Portugal.
The video shows the log, with thousands of the creatures moving about as the camera zooms in and gets a closer look.
The footage was originally posted on Facebook, with the source calling the sight of the shellfish “so rare” and “mesmerizing to watch.”
A local news report estimated the barnacles to be worth about £50,000 (USD$64,000). Credit: Anonymous via Storyful
