Maternal instinct: A two-year-old chimpanzee called Do Do feeds milk to Aorn, a two-month-old tiger cub
Completely at ease in each other's company, the ape's motherly instincts take over as she attentively bottle feeds the baby tiger.
Aorn gratefully laps up the milk as Do Do tenderly holds the tiger in her arms.
At one point, Do Do puts the bottle in her own mouth - almost mimicking the actions of a human mother checking to see if the milk is suitable for her offspring to consume.
For some unexplained reason Do Do is wearing a pair of denim shorts - perhaps to protect her thighs from Aorn's claws.
They were photographed at Samut Prakan Crocodile Farm and Zoo on the outskirts of Bangkok, Thailand.
