After seeing his close-up photographs of human eyes become enormously popular last year, photographer Suren Manvelyan turned to a more difficult subject: animals. He somehow managed to create a series of photographs showing the stunning eyes of animals ranging from crocodiles to horses.

Can you figure out which animals these eyes belong to? The answers, and more of these photos, can be found over on Manvelyan’s website.
