I've seen squared-off pupils on other animals as well: goats and octopus have rectangular pupils. Octopus pupils remain level with the horizon as the octopus rotates. If you look closely, you'll see that fish eyes have four small lines radiating away from the (circular) pupils at right angles; these reveal that fish eyes swivel to remain level with the horizon as well.
