The team of international scientists found very rare cave habitat in China.
Known as a humpback golden scaly freshwater fish or 'Sinocyclocheilus cyphotergous', this fish has almost all its pigment and is white like pearls.
This fish has eyes, but can hardly see the front.
The fish, described as an alien by a team of scientists, is a fish species associated with carps, nishikigoi, and goldfish, with small horns on the back.
Dr. Yauijo, a member of the Chinese Cavefish Working Group, a team of scientists at the Chinese Academy of Sciences and fish discovery, said, "It is one of the most bizarre freshwater fish and one of the rarest fish in the world." Explained.
There is no ecological data on this fish species since 1988 when this fish was first discovered. Only two samples are preserved in the museum collection.
Andy Gluzenkamp, director of the San Antonio Zoo Conservation Society, speculated that "this fish would have been a species similar to a white long whale."
Meanwhile, the research team is taking part of the sample in the laboratory of the Chinese Academy of Sciences to investigate the function of the horn
Scientists are trying to find ways to preserve the fish 's living environment because the cave ecosystem is now faced with many dangerous situations.
