Gorillas in zoo fascinated by caterpillar (VIDEO)

When we go to the zoo, we do it to look at animals like gorillas, but what about the gorillas, what do they get to look at? Caterpillars, that's what … and they love it!

A video shot at Calgary Zoo in Canada shows a group of gorillas looking fascinated as they watch a caterpillar crawling up the cage of their enclosure.

The gorillas even push each other out to the way to get a better view of the little critter and are clearly intrigued by it.

So if we are fascinated looking at gorillas which are fascinated looking at a caterpillar, the question remains, what is the caterpillar fascinated looking at?
