Why do some animals have specialized eyes?

Specialized eyes in animals are adaptations that help them survive in specific environments. For example, nocturnal animals like owls and bats have larger eyes with more rod cells, which help them see in low-light conditions. Predators like hawks have sharp, keen eyesight to spot prey from great distances. Some deep-sea creatures, like the giant squid, have large eyes that help them see in the pitch-black waters of the ocean. These adaptations enable animals to function more effectively in their habitats, whether hunting, avoiding predators, or navigating in darkness.
