There is a single [lateral line](/source/lateral_line), the upper one, which consists of tubed scales. The [pectoral fin](/source/pectoral_fin)s are roughly equal in length or longer than the [pelvic fin](/source/pelvic_fin)s. The first and second spines of the first [dorsal fin](/source/dorsal_fin) are roughly equal in height but are taller than the third spine. The last spine of the first dorsal fin is connected to the first ray of the second dorsal fin by a membrane. There are 14-15 branch fin rays in the [caudal fin](/source/caudal_fin). The front of the jaws have a band of small, sharp, conical teeth which reduces to a single series towards the rear of the jaws becoming uniserial, these back teeth and the outer row of the front teeth are a little bigger than the inner row. The largest recorded [total length](/source/total_length) in this genus is {{cvt|24|cm}} in ''N. larseni''. ==Distribution, habitat and biology== ''Nototheniops'' are found in the Southern Ocean off the [Antarctic Peninsula](/source/Antarctic_Peninsula) and in the subantarctic islands and seamounts, especially in the Atlantic and Indian sectors. They are found at depths between {{cvt|30|and|550|m}}. The larvae and juveniles are [pelagic](/source/pelagic) and it is thought they may have a long pelagic phase which helps dispersal, settling to a [benthic](/source/benthic) lifestyle as adults. They feed on [crustaceans](/source/crustaceans) such as [krill](/source/krill), [hyperiid amphipods](/source/Hyperiidae) and [mysid](/source/mysid)s, juveniles feeding on [copepods](/source/copepods). ==References== {{Reflist}} {{Taxonbar|from=Q675148}} Category:Nototheniidae Category:Taxa named by Arkady Vladimirovich Balushkin --- Adapted from the Wikipedia article [Nototheniops](https://en.wikipedia.org/wiki/Nototheniops) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Nototheniops?action=history)).
