What ability have many cave fishes lost?

Answer 1

Many cave fishes have lost the ability to see due to their adaptation to dark, subterranean environments. Over generations, the lack of light has rendered their eyes non-functional or greatly reduced in size. Instead of vision, these fish have developed enhanced sensory adaptations, such as heightened taste and smell, to navigate and find food in their dark habitats. This evolutionary change exemplifies how species can adapt to extreme environments by losing certain traits.
