Found fish 'see through' in Amazon

Researchers have discovered a new, transparent fish in the Amazon rainforest.

Both small and transparent, this fish has been "hidden" for several decades.

On the outside, this fish has an average length of about 17mm. This is the reason why scientists find them to believe that this is the smallest fish known to science.

In fact, perhaps because of the transparent structure, which is small in size, scientists have not discovered them in the past few decades. Maybe this is a nocturnal species.

The new species was discovered in the Rio Negro, an Amazon tributary, and named Cyanogaster noctivage (night wandering with green belly).
