Question

name an animal having rudimentary eyes

Answer 1

I think it is "Tuatara".

Answer 2

The answer is TUATARA because it is known for having a pineal complex which is developed as an outgrowth of the brain. Tuatara is a lizard-like animal. And this eye is also known as a third eye, which is located below the skin between the parietal bones of the skull roof. This eye has lens, retina, and neural connections to the brain but does not form the image.
