ELi5: why do carnivorous dinosaurs have eyes on the side of their head?
In: 22
The idea that predators have eyes on the front & prey have eyes on the side is really only limited to mammals & some birds. The larger generalisation for most animals is that their eye position depends where attacks can come from. Most sea creatures have eyes on the side of their head, whether they’re predator or prey, because they live in an environment where attacks can come from any angle, so they need a wider field of vision, at the cost of binocular vision. Animals that live on earth might benefit from the depth perception that comes from binocular vision, at the cost of a wider field of vision.
