A new eyeless and scaleless fish species has been discovered on a small island in Ha Long Bay in the Gulf of Tonkin, Vietnam, according to Live Science reports, December 2, 2012.

Fauna & Flora International (FFI), the leading NGO for limestone karst and cave conservation in Asia-Pacific Region said the newly described fish, a type of loach, has been named Draconectes narinosus, derived from Greek words “drakon” for dragon, “nectes” for swimmer and the Latin word “narinosus,” which means “who has large nostrils.”

Based on reports, its lack of eyes and scales are actually common adaptations for animals that came from the darkness of deep limestone caverns.

Moreover, FFI mentioned it’s amazing that the fish has survived in such a small, precariously positioned habitat. Van Gio Island is a formation in Ha Long Bay with long, narrow arms that have a maximum width of just 1,300 feet (400 meters).

However, recent reports said scientists do not know yet whether there are analogous species on nearby islands, or whether this is the only surviving species in its genus.
