Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 1; Afterflossenstacheln: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels broadly fringed, shorter than head, unbranched and without tubercles, but with a well visible, broad basal membrane; mandibular barbels with rather numerous, long, simple and tuberculate ramifications; mandibular teeth very long, numbering 6-10 (10 in the lectotype); denticulations on pectoral-fin spines finer and more close-set on outer than on inner margin; dorsal-fin spine finely denticulate on anterior margin; humeral process deep, granulose, its lower margin convex, ending in a blunt point and not keeled; adipose fin normally developed and distinctly separated from rayed dorsal fin, its posterior margin truncate; caudal fin strongly developed as compared to that of other species (Ref. 57223).
Coloration: general appearance greyish, ventral regions lighter; outer margins of caudal fin black-edged (Ref. 57223).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum reported size: 400mm TL, 310mm SL (Ref. 57223).
