horses' eye pupils

A friend just sent me this link which I found interesting:
http://m.livescience.com/51762-why-do-sheeps-and-horses-have-elongated-pupils-video.html

Are you perceptive enough to have noticed the change in position of the pupil? I hadn’t… maybe because when I’m eye-to-eye with my horse, his head is in one typical position? Off to the barn to raise and lower my horse’s head and see the effect in action…

Considering that whoever posted that video wrote “sheeps” I question the video’s authority. Accuracy is all when science is involved.

Nonetheless, you may find it interesting!

Have you noticed that your horse’s pupils stay horizontal to the ground, despite the altitude of the head?

Sorry if you don’t find it useful enough to override your dislike of the author’s spelling mistake (or colloquialism).

It is true they do. I don’t know that people really notice it per say but they sure would note something was amiss if they saw a horse with the pupil not horizontal to the ground but horizontal to the eye instead!

As to sheeps. I think it is common to say sheeps in some country when referring to all breeds of sheep.

Poor grammar is not a colloquialism, it’s just incorrect usage.

The fact that the video is from Duke University it more credibility; the fact that the person who posted it couldn’t copy “sheep” correctly does not!

Also “interesting” that the narrator says our pupils can’t do what sheep’s and horses’ do – well, duh! Our pupils are round, so how they can be parallel to the ground?

“Sheeps” is not correct English in any country where English is the native language –

–but then neither is “per say.” It’s “per se.”
