Interesting facts about blinking

All creatures great and small blink — except for fish, snakes and other animals without eyelids. Then there are some special creatures — perhaps most famously hamsters — that wink, blinking only one eye at a time. In 1927, W.P. Blount published the definitive guide to blinking in the animal kingdom titled “Studies of the Movements of the Eyelids of Animals: Blinking.” Among Blount’s findings: Sudanese monkeys blink like crazy, rats blink when they sneeze and goats blink at intervals of 30 to 60 seconds.
