There is a species of catfish that has no eyes only living in Mexico and has been discovered in a deep limestone cave in Texas (USA).
The tiny pink catfish , only 8cm long, without eyes , the scientific name is Prietella phreatophila , in Texas has long "dodged" scientists.
Last May, they discovered them in a deep limestone cave in Amistad National Reconstruction Area, Texas.
Mexican eyeless catfish.
The researchers found a pair of pale pink fish near Del Rio, which brought them back to the San Antonio Zoo's Research and Research Department.
The eyeless catfish only lives on the seabed. Their discovery in Texas reinforces the hypothesis that aquifers in Texas and Mexico are connected.
This fish lives in a deep limestone cave in Amistad National Reconstruction Area, Texas.
Mr. Jack Johnson. director of the conservation area in Amistad said:
"I see these fish just as they do in Mexico. It's small, pink and has no eyes. Its skin is milky, showing blood inside."
"They only live in deep water, especially Edwards-Trinity aquifers in the Rio Grande basin in Texas and Coahuila, Mexico," - Jack Johnson said.
Aquifer is the habitat of this rare species, also threatened by environmental pollution. Endangered catfishes are in danger of extinction. Their health shows the sustainability of aquifers and human water use.
The eye-catching catfish will be nourished in an environment that is naturally designed in San Antonio Zoo.
Fish are wide mouth.
Adding more eye-free catfish to Mexico, the US currently owns three species of non-eye catfish found in Texas. In which there are toothless catfish and fish on big mouth.
