Do fish need sunlight to survive?

    No. There are fish that reside in the twilight zone of the ocean where very little light reaches this zone. In fact, the light that reaches this zone is so little that photosynthesis is not even supported.

    No. There are many fish species that live deep in the ocean where there is no light at all. Deep sea fish include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, and viperfish.
