Eye Shape Reveals Whether Animals Are Predators Or Prey

The eyes really are the window to the soul

A new study has discovered that an animal’s pupil shape can tell us whether they are a hunter or the hunted.

The research found four pupil shapes that corresponded to certain animal behaviours and characteristics:

Vertically elongated pupils were found in most small ambush predators, like the lynx.

Most predators that are active during daylight hours, like humans, were found to have a circular pupil.

Those that are active during both day and night, like the domestic cat, typically have vertical pupils.

Finally, grazing animals, like sheep, were most likely to have horizontal pupils.
