That's a very common myth. It's FAR bigger than a pea and definitely bigger than a walnut.
WARNING DO NOT LOOK IF YOU ARE SQUEAMISH
Here is a website with photos of a dissection. Necropsy: Equine Head Dissection - Cristy Cumberworth Equine Photography
I found the photos interesting.
I'm currently taking an Equine Behavior class and some other myths we talked about were:
-Horses do not think
-Horses have no sense of concept
-Horses are colorblind
-Horses can not transfer information from one eye to the other
These are not true.
Another interesting fact is that horses can actually see better in overcast conditions rather than sunny. This has to do with the high proportion of rods and cones 20:1. And they have excellent night vision.
I enjoy this class haha
