Why do cats have vertical pupils? - Emma Bryce

Follow
TED-Ed

Dive into the incredible diversity of animal pupils, and how the different shapes indicate the animal’s role in an ecosystem.



Peering into the eyes of different animals, you’ll see some extraordinarily shaped pupils. House cats, for one, are twilight hunters with vertically elongated pupils. Many grazing animals, like goats, have rectangular pupils. Other animals have crescent or heartshaped pupils. So, what’s going on? Why are there so many different pupil shapes? Emma Bryce digs into the science of animal vision.
