These remarkable photographs show a tiny but daring frog in Indonesia playing with the jaws of death as he carelessly climbs into the mouth of a crocodile.

The unsuspecting amphibian was seen perched on top of a baby saltwater crocodile's nose with its hands in his mouth - seemingly unaware of the dangers involved.

One false move and it could have been the end of the frog, but remarkably the crocodile decided to forge a friendship rather than make the tiny creature his lunch.
