Description
The northern cavefish is a blind cavefish (Amblyopsidae) from underground water systems in the eastern United States. The species is pinkish-white and pigmentless and lacks functional eyes, an adaptation to life in complete darkness; yet it responds to light and swims away from it. With rows of sensitive sensory papillae on head and body it probes its surroundings. It feeds on small crustaceans and other cave life. Owing to its restricted range it is considered near threatened. The species is harmless to humans.
