This spectacular video of divers swimming with an enormous ocean sunfish has gone viral since it was posted on YouTube by photographer Miguel Pereira. The incredible footage shows the divers being dwarfed by this floating giant just off the coast of Santa Maria Island in Portugal.
These gentle creature, also known as Mola mola, are the largest known bony fish in the world and can weigh up to 5,000 pounds (2,268 kilograms). But despite their intimidating size, sunfish are actually harmless to humans. Amazingly, the bulk of this ocean beast’s diet is jellyfish, which are low in both energy and nutrients. Watch, and please share the wonder!
