Magnisudis atlantica
Unique Characteristics: Pectoral fins short, longest fin ray shorter than anal-fin base. Large mandibular teeth fixed or flexible and with smooth edges. Pelvic-fin origins behind or only slightly in front of a vertical from first dorsal-fin ray (by less than one length of dorsal-fin base); pelvic-fin origins slightly before or behind a vertical from first dorsal-fin ray. Ventral adipose fin between vent and anal fin absent. Body scaled, but scales very delicate and easily shed. Anal-fin rays 21-26. Gill rakers on first arch formed by 3-10 slender, flexible needle-like filaments on bony bases; gill rakers probably not lost in adults. Lateral-line scales unpierced by holes. In adults and subadults, 4-6 horizontal rows of scales covering each anterior lateral-line section. 3-4 dark peritoneal sections in young. Maximum length more than 45.0 cm standard length (FAO 2020).
