<em>Neocyttus acanthorhynchus</em> is a deep-sea saltwater fish classified within the family Oreosomatidae, the oreos, a group of deep-water marine fishes distributed across the Southern Hemisphere and parts of the northern deep ocean. This species typically attains a maximum length of approximately 15.2 cm and has been recorded at depths ranging from approximately 790 to 900 meters, placing it firmly within the bathyal zone of the deep sea. Oreosomatidae is characterized by members with compressed, oval-bodied forms, prominent bony tubercles or ridges on the head and body, and large eyes adapted to the low-light conditions of the deep ocean. <em>Neocyttus acanthorhynchus</em> inhabits deep continental slope and seamount environments, where it occupies the midwater and demersal zones associated with bathyal habitats. Oreos are generally carnivorous, feeding on zooplankton, crustaceans, and small fishes encountered in the deep water column or near the seafloor. Several oreo species in the Southern Ocean and adjacent waters support commercial deep-sea trawl fisheries, and their slow growth rates and late maturity make them potentially vulnerable to overexploitation. While <em>Neocyttus acanthorhynchus</em> may not itself be a target species, it is part of the ecological community affected by deep-water demersal fisheries in its range. Details of broader habitat and range for this species remain limited in the ichthyological literature.
