Body compressed and fairly deep, deepest at origin of first dorsal fin. Caudal fin elongate and tapered. Head round. Mouth small and inferior. Snout elongate and strongly downturned; hence vernacular name “elefant fish" or “Pez elefante". Labial furrows and dermal fringes well developed around mouth. Frontal clasper present in male. A lateral line running close to dorsal profile, connecting anteriorly with well developed cephalic sensory canal system. First dorsal fin, originating slightly before pectoral fin origin with a large serrated cartilaginous spine. Pectoral fin very large, its tip beyond pelvic fin origin. Pelvic fin origin slightly anterior to 2nd dorsal fin origin, both fins triangular in shape, 2nd dorsal fin larger than pelvic fin. Anal fin situated closely to caudal fin with a deep notch in between.
Distribution:
Both Chilean and Argentine Patagonia, chiefly on continental shelf.
Remarks:
Closely related to Callorhynchus millii from New Zealand and Australia, and C. capensis from South Africa. Three species are presently recognized, though Nelson (1976) recognized 4 species in Callorhynchus. They are commonly used for “fish and chips".
