Goatucation Returns - Why Are Goats Eyes the Way They Are?

Yes, I know it is Saturday and not usually a day for learning.
But I was asked a question yesterday and I thought it would be rude not to answer it.

I am not a rude goat.
I am not Abby.

One of my lovely readers asked why goats' pupils are horizontal instead of vertical like your human eyes.



If you look at my close up you can see that my eyes are indeed very different from yours.


There are a couple of reasons for this. But first I would like to point out a very interesting fact; goats' pupils are actually rectangular. 
You can see that very clearly in the photo.

Is that not fascinating?

The first reason for our eyes (and the eyes of other hooved animals) being this way is to increase our peripheral depth perception so that we can see what is off to the sides better in 3D. 

The second reason is our eyes allow us to see better at night. This is obviously more important for my wild cousins than it is for us goats here on the Farm. We don't have to worry about being out at night and watching for predators. We have a nice safe and warm barn to sleep in.

Our vision covers 320 - 340 degrees as opposed to human eyesight which covers 160 - 210 degrees. This lets us see almost all the way around us without moving our heads.

Now you are jealous, aren't you?

I hope you enjoyed this Goatucation post today. I think I will goatucate you whenever I receive a question. So if you have a question about goats just ask away.

  1. You truly are a very wise goat Pricilla! Isn't it nice being a domesticated goat--no worries of wolves and bears and stuff like that!

  2. That is a great Goatucation post today. Very interesting about the eyes. We knew that horses can see on the sides but didn't realize that goats could too. No wonder Peepers has her eyes on us all the time.
    Have a great Saturday.

  3. Thank you, Pricilla! I've often wondered about your eyes and just marvel at how wonderful it is that you've been given such a great asset... The better to see the Publisher coming with a basket of apples, too!

  4. We've always wondered that too so thanks for the goatucation today! Your eyes like that make the goat stare of death much more effective too!

  5. Thank you, Pricilla. Very goatucational. And yes, very jealous because it would be very handy to see the boss coming up from behind you without having to turn your head (you know, for when you might be at work looking at goats instead of something your boss thinks you should be doing...)

  7. Oh, that is very interesting. I was wondering about that. They should have marbles that look like "goat's eyes"--sorta like "cat's eyes". Wouldn't that be cool??
