Eye Shapes Of The Animal World Hint At Differences In Our Lifestyles
#1
Take a close look at a house cat's eyes and you'll see pupils that look like vertical slits. But a tiger has round pupils — like humans do. And the eyes of other animals, like goats and horses, have slits that are horizontal.

Scientists have now done the first comprehensive study of these three kinds of pupils. The shape of the animal's pupil, it turns out, is closely related to the animal's size and whether it's a predator or prey.

I thought this was very interesting and could be of help when designing xenosophonts or new terragen species.
