Blind cavefish evolved higher foraging responses to chemo- and mechanostimuli.

In nature, animals must navigate to forage according to their sensory inputs. Different species use different sensory modalities to locate food efficiently. For teleosts, food emits visual, mechanical, chemical, and/or possibly weak-electrical signals, which can be detected by optic, auditory/lateral line, and olfactory/taste buds sensory systems.

Blind cavefish evolved food-searching behavior without changing sensory modality compared with sighted conspecies in the dark.
