Nestled under the magnificent mane of his father, the little lion cub gives a growl so gentle it would fail to startle a passing gazelle.
But when he grows up he'll be able to roar just like daddy.
Not that this particular parent looked in the mood for exercising his vocal cords. Or indeed any other part of his mighty frame.
Mane attraction: The enormous lion wakes from his slumber as his cub emits a tiny growl
He had been trying to enjoy a catnap when his offspring was disturbed by the approach of a Land Rover carrying tourists on safari in Tanzania.
One of the party, Martina Neumann, took this remarkable photograph. She said: 'It was very funny to look at because the lion was so grumpy and tired that it reminded me of many of my friends when they were new dads having to cope with their children.
I bet he didn't thank us one bit for ruining his brief moment of peace.'
