"눈이 없는 동물은 시각이 있습니까?"

Translation: Does an animal without eyes have a sense of sight?

[SvedishPlumber]

Nope

[BobPancakes]

Actually there are animals like worms that don't have eyes but have photo-sensitive cells on their skin that tell them which way the light is shining. So the answer in some cases is yes.

[Noah459171]

Bats and whales use echolocation. Sharks and platypuses use electroreception. Pit viper snakes can see infrared. These animals probably experience these similarly to sight but they don't need to use their eyes for these.

[MariosK.Zi]

Why?
