COSEWIC Assessment and Update Status Report on the Pighead Prickleback Acantholumpenus mackayi in Canada

This marine fish is a member of the family Stichaeidae. It has a slender, eel-like body with numerous dorsal rays extending along the full length of its back. It is distinguished from other stichaeids by thickened lips, stout head, and proportionally smaller eyes. Although the proper common name for this prickleback is the pighead (American Fisheries Society), this species is sometimes called the blackline prickleback.
