A tiger shark has shown what it would be like to be eaten alive after swallowing a phone which was recording a video.

The predator gobbled up the iPhone when it was accidentally dropped in the water while tourists watched a feeding session from a boat in the Bahamas.

Footage showed the shark’s jaws clamping down around the device before revealing the interior of the creature’s mouth lined with pulsating gills.

The phone belonged to Dave Finch who was captaining the excursion operated by Dolphin Dream Team. 

His friend, Ken Kiefer, an underwater photographer, was working with him on the shark tour.

He wrote on Facebook: “This devious girl – known by some as Jitterbug and by others as Buttface – grabbed Finch’s camera and was trying to get some selfies.”

Tiger sharks are known as unfussy eaters, with the stomach contents of captured animals revealing stingrays, seals, birds, car number plates and tyres.
