Goat Eyes

From answers.com:

Goats (and most other animals with hoofs) have horizontal slits which are nearly rectangular when dilated. This gives goats vision covering 320 - 340 degrees; this means they can see virtually all around them without having to move (humans have vision covering 160 - 210 degrees). Consequently, animals with rectangular eyes can see better at night due to having larger pupils that can be closed more tightly during the day to restrict light. Interestingly, octopuses also have rectangular pupils.
