Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 12 - 13; Spine anali: 3; Raggi anali molli: 11 - 12. Diagnosis: pectoral fin with 4 threadlike filaments (Ref. 57402, 81658). Pectoral fin inserted very low on body, generally somewhat longer than upper part of fin (Ref. 57402).

Biologia     Glossario (es. epibenthic)

Occurs in shallow coastal waters, over sandy and muddy bottoms, sometimes in brackish habitats (Ref. 57343, 81658). Enters estuaries (Ref. 57402), occasionally caught in fresh water (Ref. 57402, 81658). Very large specimens are only found in marine waters (Ref. 81658). Feeds on crustaceans and fishes (Ref. 10799, 81658). Flesh fairly tasteful (Ref. 57402).
