A diver discovered a huge school of hammerhead sharks swimming in a group together while waiting for their evening hunt at Isla Wolf in the Galapagos.
The footage, filmed on March 28, shows dozens of hammerheads seemingly swimming in place as they pass through the current.
A scar can be seen on one of the female's heads, likely from mating.
The filmer, Todd Kortte, commented: "The current was moving at an extreme fast pace. So much that the Hammerhead sharks appear to be swimming in place."
