Family Amblyopsidae--Cavefish Family
These small fishes have very small or nonfunctioning eyes, no or
very tiny pelvic fins, a flattened head, anal and urogenital openings
under and between the gills, embedded cycloid scales and one dorsal
fin. They have large sensory bumps on the head, body and caudal fin
which help them to compensate for their poor vision.
