QUIT monkeying around!
A mischievous long-tailed macaque monkey has offered up what appears to be a smile, complete with bared teeth, for a “hidden” camera on the island of Borneo.
The snap was posted on Twitter by the Houston Zoo, partners of the Danau Girang Field Center in Borneo.
“Looks like someone knew about the ‘hidden’ cameras,” the Houston Zoo Tweeted.
However what appears to be a grin to the human eye is actually a sign of aggression or anger.
