An order of fishes containing the cods, codlings, codlets, grenadiers, and hakes. The Gadiformes plus the orders Ophidiiformes (pearfishes, cusk-eels, and brotulas), Batrachoidiformes (toadfishes), and Lophiiformes (anglerfishes), collectively called the Anacanthini, are thought by some authors to be a monophyletic lineage but the concept is doubted by others. The group is characterized by the absence of a myodome (a cavity in the postorbital region of the skull in which lodge the muscles of the eye; actinopterygian fishes typically have a well-developed myodome); absence of parapophyses (singular parapophysis; a long, transverse process arising from the abdominal vertebral centrum, which serves to support epipleural ribs and, in Gadidae, the gas bladder; also called transverse process) on at least the first three vertebrae; and insertion of the first few pairs of ribs in cavities of the vertebral centra rather than on the parapophyses.
