Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Snout relatively long, length about 2.5 in HL, with blunt tip and anterolateral margin incompletely supported by bone. Suborbital ridge with 2 rows of thick, stout, modified scales. Orbit large, about 2.0 in snout length. Mouth large with rictus more than 2/3 length of upper jaw. Opercular opening is far forward, with a free fold across isthmus. Underside of head scaled. Nasal fossa fully scaled. Body scales large, with 5-7 sharp, divergent rows of spinules. The light organ is small with a short and slender blackish streak. There are numerous prominent saddle markings on body; dusky triangular marking anteriorly on isthmus (Ref. 54421).
