New Eyeless Fish
A cave-dwelling fish with no eyes and no scales has been discovered on a tiny island in Vietnam's scenic Ha Long Bay, according to conservation group Fauna & Flora International.
The newly described fish, a type of loach, has been named Draconectes narinosus, which derives from the Greek words for dragon "drakon" and swimmer "nectes," as well as the Latin word "narinosus," which means "who has large nostrils."
Its lack of eyes and scales are actually common adaptations for animals that have evolved in the darkness of deep limestone caverns. Like other cave fish, D. narinosus is limited to a life in freshwater, which means it is likely confined to a system of subterranean caves on Van Gio Island, unable to swim out into the surrounding sea.
