Dieidolycus adocetus

<em>Dieidolycus adocetus</em> is a saltwater fish of the family Zoarcidae, the eelpouts, a diverse family of elongate, eel-like fishes found predominantly in cold marine waters of the northern and southern hemispheres. This species has been recorded at depths of approximately 1,957 metres, placing it firmly in the bathypelagic or bathybenthic zone of the deep sea. Zoarcid fishes are adapted to the extreme conditions of the deep ocean, including near-freezing temperatures, high pressure, and limited food availability. Eelpouts typically feed on benthic invertebrates such as polychaete worms, crustaceans, and echinoderms. No maximum length data are currently available for <em>Dieidolycus adocetus</em>. The family Zoarcidae includes numerous species from the North Pacific, North Atlantic, and deep-sea habitats globally. Details of the specific habitat associations and geographic range of this species remain limited in the ichthyological literature.
