This girl was only 2 weeks old when I took this picture. When she grows up her eyes will slowly move closer to the top of her head, and that placement is found in most prey animals. Goats' rectangular pupils help them survey their surroundings and if they see anything that might be considered a threat, they dart.
Humans have 210 degree field of vision. 114 degrees are bifocal, meaning that we see in 3D and can perceive depth pretty accurately. Goats have 340 degree vision. They can see behind them without turning their head. Most of that is monofocal or in 2D so they sacrifice depth perception to be able to see around them. Goats can see further than humans and they're incredibly sensitive to motion so sneaking up on a goat is really tough. However, it's not all monofocal, they have about 40 degrees in front of them that is in 3D and it's pretty accurate. This bifocal vision helps them when they make the decision to run for their lives. The rugged terrain needs to be traversed carefully and slipping or falling while running away is not an option, so having some bifocal vision is really important especially during jumps.
Now goats are grazing animals. Their noses touch the ground when they munch on the grass, however, that doesn't make it any easier to sneak up on them. When they eat they don't look at the ground in front of them and the sky behind them. The trick that they employ is kinda creepy if you pay attention. But more on that tomorrow.
Zebras are very fast-moving animals, and can reach speeds of up to 65kmph when galloping across the plains. This is just fast enough to outpace predators such as lions. Foals can run with the herd within a few hours of birth.
