Species of the subfamily Paralepidinae are distinguished in having cycloid scales on the head and the body. Body elongate and slender, subcylindrical to laterally compressed. Unpaired fins without spines; 1 short dorsal fin, 8-11 rays, pelvic-fin rays I, 8, both set behind midpoint of body; anal-fin rays 20-35, its origin distinctly behind dorsal fin; pectoral-fin rays I, 10-16, set low on body; principal caudal-fin rays 9+10; a dorsal adipose fin always present above last rays of anal fin. Brachiostegal rays 8, vertebrae 60-89. Snout pointed; mouth terminal, the lower jaw projecting, with a non-ossified process. Two nostrils. Alternating fixed and depressible fang- like teeth on lower jaw, palatines and ectopterygoid (roof of mouth); premaxillary with 3-5 fangs at tip followed by small saw- like canines. Gill rakers reduced to teeth or spines in multiple series on a bony shield. Scales cycloid and easily shed. No light organs in antarctic species. No swim-bladder. Hermaphroditic. Four genera and 9 species of medium-sized fishes, ranging from 20 cm to over 50 cm SL. Three genera and 4 species in CCAMLR area. Meso- to bathypelagic, swift swimming predators.
