Photographs of a 'macho' marsupial standing in a creek in Western Australia have gone viral online.
The 6ft 5in kangaroo was encountered by 27-year-old Jackson Vincent while he was out walking his dog near Boodjidup Creek earlier this week.
The creature's incredible rippling muscles gave it the appearance of a professional bodybuilder.
"I have been going to that creek since I was a little boy and there have always been kangaroos on the property," said Vincent. "I was walking my dog and we saw this huge roo standing in the water. "
"I have never seen a kangaroo standing in the water like that, we could just see his head at first, and he was one of the biggest I have ever seen. As I ran around him to take a picture he came closer and that was when I realised he was coming right at me and he was really big."
While kangaroos generally don't tend to attack humans unless provoked, this one was so massive that it was difficult to do anything other than back away as it approached.
"He looked to be at least two meters (6ft 5in) tall or taller and must have weighed at least 100 kg (16st)," said Vincent. "He had a really big body and was taller than me. There are a lot of roos at my grandma's place but I have never seen one that muscular before - he was a big macho male."
