Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 90-107; Épines anales 0; Rayons mous anaux: 70 - 90. Caudal sharply rounded but not readily distinguishable from dorsal and anal fins. Pelvic fins minute.
Found on silty or sandy bottoms (Ref. 27436). Moves into shallow water at night to feed on marine worms, crustaceans, small bivalves, and brittle stars (Ref. 6885, 27436). Few live over 5 years (Ref. 6885). If used live as bait, it attracts large rockfishes, greenlings or codfishes (Ref. 27436). Flesh considered good but not esteemed (Ref. 27436).
