Diagnosis: This species is distinguished by the following characters: anterior cavities of lateral ethmoids (where the olfactory bulb is housed) greatly developed; bony excrescence of posterolateral process of lateral ethmoids prominent, completely closing the lateral fenestrae; basioccipital with a laminar bony crest bordering the anterior foramen of aortic tunnel (Ref. 86580).
Abundant on the continental shelf (Ref. 9271). Utilized fresh or salted, but rarely consumed (Ref. 9271). Demersal species that inhabits sandy substrates in coastal waters up to 60m deep. May be caught in nets and purse seines along with other fishes. It is sold fresh (Ref. 55763).
