Etymology: Plagiogeneion: Greek, plagios = oblique + Greek, geny, genyos, diminutive = face (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 200 - 500 m (Ref. 115123). Deep-water; 22°S - 40°S, 14°E - 170°E
Indo-West Pacific: St. Paul and Amsterdam Islands, southern Australia, and New Zealand. Southeast Atlantic: Vema Seamount west of Cape Town and off Algoa Bay, and Walvis Bay in Namibia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 5325); common length : 40.0 cm TL male/unsexed; (Ref. 115123); max. reported age: 10 years (Ref. 35378)
Adults occur near sandy or muddy bottom in deep water. Feeds on larger zooplankton (Ref. 3394). Marketed fresh or frozen and proves to be an excellent foodfish (Ref. 115123).
