Etymology: Macrourus: Greek, makroura = great tail (Ref. 45335).
More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 300 - 1400 m. Deep-water; 39°S - 57°S, 62°W - 38°W (Ref. 1371)
Southwest Atlantic: so far known only from the Patagonian slope from east of the Rio de la Plata to north of the Falkland Islands and off Shag Rock west of South Georgia. It can be expected also on the west coast of Chile, but its presence there, as well as in other regions where it has been reported must be confirmed.
