Cave-Dwelling Fish Could Provide Clues to Staying Healthy with Diabetes (IMAGE)
Caption
The cave-dwelling form of Astyanax mexicanus, known as cavefish (bottom image), has lost traits such as vision and pigmentation and has acquired other traits that help them survive in dark caves with minimal food supply. Fish of the same species can also be found in surface rivers near the caves (top image).
