ucresearch:Hunter or Hunted? What Eye Shape May RevealThe eyes are the window to the soul — and the food chain, it turns out.A new study from UC Berkeley suggests that pupils can reveal whether an animal is the prey or the predator. Animals that are grazers are more likely to be prey, and typically have horizontally elongated pupils on the sides of their head. These rotatable pupils helps expand their view and detect predators that may be coming at them. Ambush predators (like snakes, domestic cats and alligators) that are closer to the ground and active at day and night, have vertical slit pupils. This increases their depth perception and gives them a better visual focus on their prey.Animals with spherical pupils (including humans, big cats and dogs) were linked to “active foragers,” or animals that chase down their prey. The researchers reason that these animals are bigger and sit higher on the ground, therefore don’t have the same visual needs. Read more about the study here. -- source link
