Have you ever noticed that there is something discordant, if not diabolical, about a goat looking at you? If so, the problem may be its eyes. Goats are unusual in that they have horizontal bar-shaped pupils. These give them great peripheral vision, and a goat can almost see behind itself without turning its head. Optics of this nature are very useful for those animals who wish to avoid a predator having them over for dinner.
Bovines and some birds also have similar pupils, but those of goats, for some reason, seem far more conspicuous.
