This is moment an irate giraffe came too close for comfort for safari tourists on a game drive in South Africa.
Dramatic mobile phone footage shows the group desperately trying to flee in their jeep as the huge animal gives chase through the wild.
In scenes reminiscent of the T-Rex chase in the film Jurassic Park, the giraffe, which towers at around 16-20ft tall, gallops behind the vehicle as terrified passangers look on.
As the jeep rounds corners and speeds under trees, the animal slips into the distance before reappearing as it gathers pace.
The group eventually lose the creature, before turning around and driving off to safety.
The close call was captured on a mobile phone camera by passenger Henk Roos, who uploaded the clip to YouTube where it has gone viral with more than 15,600 hits.
In a post underneath the video, he wrote: “After an amazing wedding we went on a game drive and a hormonal Giraffe started to chase our jeep.
“After about 5km of being chased I started recording the chase on my phone. You can see how he gets closer and closer after every turn.
“We started to run out of road and the ranger banged on the side of the jeep to scare him off. We started to make a noise and he stopped.
“Just in time as we had to make a 4 point turn to continue on the road!”
