It lurks just inches below the surface coiled and ready to strike – and yet you wouldn’t know it was there.
These remarkable images show the enormous 26-foot (eight metre) anacondas of Mato Grosso in Brazil searching for prey in the murky depths.
They were captured by brave diver and snake enthusiast Franco Banfi, 53, who joined the beasts in their natural habitat armed only with a camera.
In another shot, Banfi gets up close to a huge anaconda that is lying on the riverbank and glistening in the ferocious tropical heat.
Thankfully for the photographer, it had just gobbled up a capybara rodent and wasn’t interested in devouring him as a second course.
Banfi, a father-of-two from Switzerland, said: ‘As the snake had just eaten it didn’t take much interest in us.
‘Everything is possible but I don’t think it would have eaten us. I was very close, I could have touched it if I wanted to.’
