Mexican Blind Cave Fish
fresh water in northern and central Mexico
Fish with no Eyes or Pigmentation
The blind and colourless cave fish live in deep, totally dark grottos. As eyes are useless in the extreme darkness they wasted away gradually. These fish use their sense of smell and Weberian apparatus to get their bearings in total darkness.
As a cave fish can’t tell the difference between day or night it is active round the clock. It eats insects, small shellfish and worms
