The glassy look and sinister smile of an orangutan
Orangutans are one of the most intelligent animals in the world, and they are also the closest to humans in terms of DNA homology. They can even use primitive tools and they have their own language! In general, these guys are really very similar to people. And sometimes even too much. For example, this handsome redhead... reminds me of Hannibal Lecter. He calmly watches us through the glass, as if studying and understanding every word. His glassy gaze literally pierces, and the sinister grin ... frightens.
