}} The abyssal halosaur (Halosauropsis macrochir) is a species of bottom-dwelling, deep-sea fish in the family Halosauridae that is found in all oceans at depths of 1100 to 3500 meters.[1][2] It is the only member of its genus.[3] Abyssal halosaur can reach total length of at least {{convert|76|cm}} and weight in excess of {{convert|400|g}}. Berstad et al.[2] could not sex fish smaller than 25 cm, giving an indication about length at maturation. Abyssal halosaur are long-lived, with maximum reported age of 36 years, although individuals sampled on the Mid-Atlantic Ridge were mostly <20 years. It appears to be an opportunistic feeder, mostly taking epibenthos and small fish.[2] References1. ^{{FishBase |genus= Halosauropsis |species= macrochir | month = June| year = 2011}} {{Taxonbar|from=Q145305}}{{Notacanthiformes-stub}}2. ^1 2 {{Cite journal | last1 = Bergstad | first1 = O.
