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).

Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt): 6-7; Afterflossenweichstrahlen: 6; Wirbelzahl: 29 - 32. Distinguished by the latero-sensory system which is restricted to LL1 and LL2, the pectoral fin with two branched rays, the absence of pelvic fins and girdle, the reduced jaws and pharyngeal dentition, the presence of six to seven interopercular odontodes, the absence of a lateral series of spots, the presence of a small dark spot on the ventral surface of the mandibular symphysis, the narrow comma-shaped palatine, the absence of procurrent rays anterior to the dorsal and anal fins, the position of insertion of the first dorsal-fin pterygiophore and the presence of a single pair of pleural ribs (Ref. 91084).
Found in places with mud and roots of aquatic plants of a small stream, mainly composed of sandbanks (Ref. 116750).
