a family of marine fishes of the order Allotriog-nathi (Lampridiformes). The only species is the opah, or moonfish (Lampris regius), which is sometimes incorrectly identified as the ocean sunfish. The body is long and strongly compressed laterally. The opah is medium blue with small silvery white spots. It measures up to 2 m. It has small scales and a small, toothless mouth. The fins are bright red and soft-rayed. The pectoral and pelvic fins are long and sickle-shaped; the dorsal fin has a tall anterior sickle-shaped lobe. The opah is distributed in the temperate and tropical waters of the Atlantic and Pacific oceans, staying far from the shores. It is usually found at depths of 100 to 400 m. The opah feeds on plankton.

Caption: Popular on some seafood menus, the opah, one held here by Nick Wegner, is proposed to be about as close to a full-body warm-blooded fish as science has yet discovered.
The opah tag record closely resembles the relatively constant temperature noted for lamnid sharks, despite the independence of stomach temperature with ambient water for these endothermic sharks as reported by Carey et al.
Although the programming of the tag on the opah precludes such fine-scale analyses of diving behavior, the available data are not inconsistent with the mako tracks in the study of Klimley et al.
The temperatures and dive depths recorded by the opah tag and both white marlin tags after apparent ingestion share similarities, yet also contain sufficient information to indicate the different identities of the ingesting organisms.
