Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 12 - 14; Épines anales: 0; Rayons mous anaux: 10 - 12. Dorsal part of body without prickles, belly covered with prickles (Ref. 559). Greenish or dark grey above, silvery white below (Ref. 4919). Distinguished from other Lagocephalus species by the black gill opening (Ref. 559).
