Etymology: Potamoglanis: Derived from the Greek potamo, means river; the gods of rivers in the Greek mythology, and from glanis, means catfish; anhanga: Named for an Amazonian Anhangá legend, a spirit that lives in the woods, protector of animals. Its presence can be detected by a whistle and thereafter, the animal that was being hunted disappears. Anhangá is thus regarded as a protector of forest life. A noun in apposition (Ref. 91084).
