What type of shark is blind?

There is no known species of shark that is completely blind. Sharks have excellent vision, even in low-light conditions.

However, some sharks may have impaired vision due to:

* Habitat: Sharks that live in deep, dark environments may have less reliance on vision and more on other senses like smell and electroreception.

* Injury: Sharks can be injured in the wild, which could affect their vision.

* Age: As sharks age, their vision may decline.

It's important to note that even sharks with impaired vision can still be quite effective hunters, thanks to their highly developed other senses.
