Anguila ciega  (Ophisternon infernale)

Biology

The Anguila ciega builds mucus-lined burrows in organic rich sediments within the freshwater part of the aquifer. This species is able to tolerate low oxygen concentration levels and can even breathe atmospheric oxygen. The diet is thought to primarily comprise stygobitic shrimp (Creaseria morleyi), and reproduction is reportedly oviparous, or egg-laying (2).
