Question

What kind of sensory adaptation would you hypothesize the cave fish has to allow it to navigate in a cave, including catching and eating food.

Answer 1

I think  the kind of sensory adaptation that i would hypothesize is that the cave fish has special sense organs on the surface of its body that responds to the presence of different chemicals in the water environment. This trait would be analogous (serving similar function but with a different evolutionary origin) to our sense of smell.
