Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 8; Spine anali: 0; Raggi anali molli: 7. Remarkable for its highly tortuous lateral line; its nostrils also rather peculiar (Ref. 3157).
Found on soft bottom (Ref. 9349). Juveniles inhabit estuaries (Ref. 9349). Makes a loud grating noise (Ref. 3157).
