GoPro and Twitter's Periscope are set to take users under the sea today (3 March) by hosting a real-time underwater livestream with great hammerhead sharks.
The event follows the pair's announcement back in January, in which they revealed that they'd decided to team up to broadacst real-time streams to viewers directly from the action cam firm's devices.
At the time, many commentators predicted that the duo's main focus would be around extreme sports due to GoPro's established partnerships with brands such like the X Games.
Today's broadcast (due to commence at 12pm EST) will take place just off the Bahamian island of Bimini and will see GoPro athletes Jeb Corliss and Roberta Mancino swim with the ocean giants.
"We want to give viewers an up-close-and-personal encounter with the great hammerhead shark – an experience that most people will never have in their life," said Corliss.
He praised Periscope as the "perfect" choice of platform for the stunt, adding: "Being able to watch a shark dive live is super exciting and people at home will get to feel what it’s like.
"As the action unfolds, people will be on the edge of their seat hoping everything goes to plan. The fact we can connect a GoPro to Periscope, take the camera 40 ft deep and beam it to the world - is super exciting! It will be a game changer for shark diving and for how we share experiences with others."
A few weeks prior to the unveiling the GoPro integration, Twitter revealed that it was to integrate Periscope streams straight into timelines, so users wouldn't have to open a seperate app or browser to watch live clips or replays.
