HL 32.2-40.0% of SL; ED 10.0-11.8; BD 27.2-31.0; SN 8.4-10.2; IO 6.1-9.5; UJ 13.8-16.1; CP 12.2-12.5; P1L 21.9-25.2; P2L 18.6-24.0; D1H 16.7-19.7; D2H 18.3-22.6; AH 19.1-21.0.
Body elongate, fairly compressed, anterodorsal profile rising from tip of snout to occiput, becoming moderately convex from occiput to first dorsal fin base, body depth about 4 times in SL. Head large, 2.8-3.0 times in SL. Eye large, about 3 times in head, longer than snout. Nostrils paired and round, posterior nostril slightly larger. Mouth oblique, protrusible maxilla extending to middle of eye. Lower jaw protruding slightly anterior to upper jaw. Jaw teeth very small or none in larger specimens. No lingual teeth on tongue. Vomer and palatines edentate or with several fine teeth. Opercular spine well ossified, pungent. Gill-rakers fairly long, awl-like. Pseudobranchiae present. Interorbital region fairly flat, its width slightly longer than snout. Scales large ctenoid, fairly deciduous. Lateral line single, running from upper insertion of opercle to caudal fin base on dorsolateral part of body. Pectoral fin moderate in size and low, nearly as long as pelvic fin in smaller specimens or longer than pelvic fin in large specimens. Pelvic fin large, nearly equal to or slightly shorter than pectoral fin, situated slightly posterior to hind insertion of pectoral fin. Bases of first dorsal, second dorsal and anal fins short. Caudal fin weakly forked, with rather deep caudal peduncle. All fin spines very strong and pungent.
Distribution:
Off Chilean coast.
Remarks:
The midwater capture of E. crassicaudus juveniles suggests that the life cycle of the species includes a pelagic stage (Mayer, 1974).
