|Etymology||Auchenipterus: From the Greek, auchenos, meaning neck and pteron, meaning fin; in reference to the long cranial shield, which gives the appearance that the dorsal fin originates at the neck region.|
|Size||202mm or 8" SL. Find near, nearer or same sized spp.|
|Identification||Looks very much like a juvenile Pangasianodon hypophthalmus to the untrained eye. More barbels and the tail pattern should give it away.|
|Sexing||Males have a genital papilla, thickened maxillary barbels and an enlarged dorsal spine. Sexually mature at 80 mm SL.|
|General Remarks||Active during the day, which makes this a very visible auchenipterid.|
