Bizarrely bulky animals are taking nature-loving tourists by storm.

First a beefy kangaroo stunned Australia, and now an equally muscly giraffe has been spotted in South Africa.

The brawny giraffe could have come straight out of Fight Club, as he shows off his muscular neck in a profile shot at sundown at the Pongola Game Reserve.

Beefy: The giraffe's oddly muscular neck was captured in all its glory in a photograph at the Pongola Game Reserve in South Africa

Giraffes use their necks to fight, so after going head-to-head - or neck-to-neck - they can end up looking extremely muscular.

And this giraffe has clearly been in his fair share of fights.

Photographer Josh Guyan, from Wiltshire, took the incredible picture.

He said: 'He's like giraffe-zilla - god help us if it's still growing!

'He is really muscly - giraffes fight with their necks, and if you look at the size of this one's neck then you can see how thick it is - he must have been in a lot of fights!

'It's really amazing, I have taken a lot of images of giraffes but I've never seen one like this before. I couldn't pass this opportunity up!' Giraffes’ long necks help them feed, keep lookout and fight. Bulls, and on occasion cows (female giraffes), have been spotted performing the elaborate ritualised fight known as ‘necking’. The fight helps the victor to establish dominance, according to the Giraffe Conservation Foundation. They repeatedly swing their long necks into each other, delivering powerful headbutts to their rival’s body.

Although they have reinforced skulls, some giraffes have been known to be knocked unconscious or even die during these battles

Both males (bulls) and females (cows) have been known to take part in the fights, which are used to establish dominance for the victor

They have reinforced skulls to help absorb the impact of the blows, but occasionally an animal is knocked unconscious or even dies during a fight.

Even with its long neck, a giraffe still has just seven vertebrae in its neck – the same as a human – but each can be up to 10 inches long.

The giraffe will join Roger the beefy red kangaroo, spotted in June, on the growing list of oddly muscular creatures.

Nine-year-old Roger the red kangaroo is also oddly muscular. He already weighs 89kg and stands 2m tall, but he hasn’t finished growing yet

The kangaroo, who lives at the Kangaroo Sanctuary Alice Springs in Australia’s Northern Territory, enjoys crushing metal buckets with his bare paws.

‘His daily exercise regime is sparring [kickboxing] with his rivals and chasing his human ‘Mum’, me,’ said his keeper, Chris Barnes.

Chris rescued Roger as a joey in 2006, after finding his mother dead on a highway.
