Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 5 - 7; Espinas anales: 0. Diagnosis: adipose fin rayed in adults, 1st ray forming a spine (not visible in juveniles); adipose-fin rays becoming visible at sizes of 90-100 mm SL, and the spine at 200 mm; dentition very well developed: premaxillary tooth plate broad (38-45% of head length), palatine dentition consisting of an elongate vomerine plate and of a dermo-palatine plate in young individuals (60-70 mm SL); palatine tooth plates narrow and long with much weaker dentition; nasal barbel long, reaching at least to anterior part of orbit; maxillary barbel very long, exceeding at least the anterior part of dorsal fin and often reaching to adipose fin; caudal-fin lobes marked by a dark band; cranial bones well developed; length of occipital process usually less than 1.4 times its width (Ref. 57126).

Biología     Glosario (por ej. epibenthic)
