Two Gorilla Brothers Emotionally Reunite After Three Years Apart (Pics & Video)

The unlikely moment came as a surprise, because this sort of moments are very uncommon among the silverback gorillas. Territorial animals, gorilla males are extremely aggressive with each other, even though they are part of the same family. It is quite unusual to see that sort of childlike behaviour in a silverback, said Tye. It is great for Alf to have an older brother to look up to and learn from and Kesho seems to enjoy being the centre of attention. It was very satisfying to see. All images credit: YouTube/ABC News
