Observations by sumersibles suggest that some ophidiid species are nocturnal and abundant in some areas. Many, perhaps all, cusk-eels produce sound, and recent acoustic surveys have found large and vocal assemblages of ophidiid fishes in some areas. Sound production most likely is related to spawning behavior. FEEDING ECOLOGY AND DIET There have been no studies of the feeding habits of the band cusk-eel. Ophidiid fishes consume benthic invertebrates, primarily small crustaceans (shrimps, amphipods, mysids, and crabs) and worms.

Feeding ecology and diet Many gadiform fishes feed on prey items occurring in the substrate, and they are assisted in their search for food by the presence of tactile barbels on their chins. Barbels are well developed in almost all of the gadids, phycids, lotids, macrourids, morids, and muraenolepidids, all of whom feed actively on benthic items. Conversely, the diet of one of the most pelagic of the gadids, the pollock (Pollachius virens), consists primarily of euphausiids and Atlantic herring, and its much-reduced barbel reflects this focus on pelagic prey.
