Dorsal spines (total): 0; Dorsal soft rays (total): 38 - 42; Anal spines: 0; Anal soft rays: 47 - 50; Vertebrae: 130. Eel-like, shallow body depth; 1 to several symphyseal fangs on dentary and premaxilla; lacking cardiform teeth, pelvic fins, and swim bladder rocker bone; a patch of ridges posteriorly on the ventral surface of the swim bladder (Ref. 34024). Precaudal vertebrae 21-25 (Ref. 34024). Branchiostegal rays: 7 (Ref. 36487).
Uncommon species (Ref. 34024). Free-living adults are found on the outer shelf, usually deeper than 64 m over muddy sand bottoms (Ref. 36487). Oviparous, with specialized vexillifer planktonic larval stage, and benthic tenuis larval stage (Ref. 36487). Maximum depth from Ref. 58018.
