lingcod

Also known as Ophiodon elongatus, Blue cod, Ling cod

The lingcod or ling cod (Ophiodon elongatus) is a fish of the greenling family Hexagrammidae. Despite its name, the lingcod is neither a cod nor a ling. It is also known as the buffalo cod, cultus cod, or Buckethead. It is the only extant member of the genus Ophiodon. A slightly larger, extinct species, Ophiodon ozymandias, is known from fossils from the Late Miocene of Southern California.
