Which animal has the largest eye in the world?

The animal with the largest eye in the world is the giant squid (Architeuthis dux). The eyes of the giant squid can reach up to 10 inches in diameter, which is larger than any other animal's eyes in the world. The size of the giant squid's eyes is an adaptation to their deep-sea habitat where there is very little light. The large eyes allow them to capture as much light as possible, which helps them to detect prey and avoid predators in their dimly lit environment.

In addition to being the largest eyes in the animal kingdom, the eyes of the giant squid are also unique in their structure. Unlike human eyes, which have a single lens, the eyes of the giant squid have a complex structure that allows them to form images in a way that is similar to a camera. They have a large, curved lens that focuses light onto a retina that contains millions of light-sensitive cells.

Studying the eyes of the giant squid has helped scientists to better understand the evolution of eyes and vision in animals. The large size and unique structure of the giant squid's eyes have also made them a subject of fascination for researchers and the general public alike.
