Mexican Blind Brotula

Photo take in a underground river system or Cenotes in the Yucatan Peninsula. This is a freshwater extremophile fish compleate blind no eyes, live under 65°F in a absolutely dark and cold atmosphere, is very rare to fine one, it lives alone or a least we have never see two or more together.
it has develop incredible sences to survive.Moves very slow to preserve energy, we think it feeds whit little shrimps and some other living organism from the cave that it can detected by the changes of density in the water.
