Why do cats pupils look the way they do? Why aren’t they round like humans?
In: Biology
Predators often have vertical pupils, while herbivorous creatures often have horizontal pupils. I’m pulling this out of the dark recesses of my brain, but I remember reading that predators focus on a single prey animal at a time, while prey spends its time scanning from left to right to determine potential threats coming from any possible direction.
I can’t remember if links are permitted in the sub or I’d direct you to a UC Berkeley study from 2015 that has more info.
There are interesting YouTube videos about this topic and probably countless articles that will come up in Google.
