Elvers continue to grow larger and become the “eels” we are familiar
The back of an eel has a greenish bronze-like color, and the
belly is white but slightly yellow.
This stage is called “yellow eel,”
perhaps because the band-like yellow color between the back and
belly of the eels might have been impressive to the person who named it.
(However, eels at this stage exhibit many color variations.)
This yellow eel stage, eels are consumed for food, such as Kabayaki.
