Holguin, Cuba, Mar 16.- A new report of blind fish in caverns of the region of Gibara, to the north of Holguin, were made by a local research group.
Jose Corella Varona, head of the team of scientific divers reported the identification of new fishes that “swim away from the light,” as described by Cuban zoologist Felipe Poey (1799-1891). The new species was identified as the type dentatus and was named n.sp.
Corella Varona said several fishes of that species were found during a study in the underwater caves of El Baga, Cristalitos de Papaya and Dos Anas, close to the towns of Caletones and Laguna Blanca, northeast Gibara.
The expert explained that one of the fishes was particularly singular and it could be that it is a new variety of blind fishes, which is commonly known as n.sp.
In Cuba, four blind fish species of the Lucifuga genus distributed irregularly across the island: subterraneus, dentatus, simile and teresinarun. There is a fifth species under study known as Lucifuga sp, and the fish found in Cristalito de Papaya.
Corella Varona, who has a long experience on the research of cave systems in Holguin and a diver, said prior to this report, there was only information from the caves of El Masío and Tanque Azul, both in Gibara.
The specialist said blind fish of the Lucifuga genus evolved to cave-dwelling species and the feed on shrimps and crustaceous.
Speleologist diver Juan Carlos Almaguer added that those species also live in both fresh and sea water and more than 90 percent of reports on the fish locate it in the western region of Cuba, except for keys and the Isle of Youth.
According to specialists, these types of blind fish can only be found in Cuba, the Bahamas and Galapagos Islands. (ACN).
