Piercing, vividly coloured and sometimes sinister, this selection of pictures shows the windows of the souls of creatures great and small.
Snapped by photographer Suren Manvelyan, the shots feature the eyes of chimpanzees to pythons to crocodiles to stingrays.
The collection comes after his hugely popular Your Beautiful Eyes series, which featured close-ups of the human eye.
Manvelyan, who has been a professional since the age of 16, also teaches physics, mathematics, geometry and astronomy in Yerevan, his city of birth.
