Kieran Bettany and his pregnant wife's trip to Colchester Zoo was made especially memorable by this special meeting with a resident orangutan.
Kayley was seven months pregnant at the time of the visit when her baby bump caught the eye of this orangutan who seemed both fascinated and moved by the bump as he tried to caress it.

Kieran said: "This was a wonderful experience however upsetting at the same time. He even had a tear run down his face".
The video was originally uploaded to YouTube in January of this year and has been watched more than 825,000 since then.
