Atlantic, Pacific, and Southern Oceans ( Fricke et al. 2020); western Pacific Ocean north to Japan (Fujii in Masuda et al. 1984), and Russian north-western Pacific Ocean ( Orlov and Tokranov 2019), to southern Bering Sea, and Gulf of Alaska (Mecklenburg et al. 2002), to Chile ( Pequeño 1989). Primarily mesopelagic and bathypelagic; depth: 0–4,000 m (13,120 ft) ( Orlov and Tokranov 2019). Considered a separate species, Poromitra rugosa (Chapman, 1939) , by some authors. However, we follow Robertson et al. (2017) and consider this P. crassiceps . This species was split into many taxa by Kotlyar (2009).
