Merlucciidae (Merluccid hakes)
Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335); tasmanicus: Named after its type locality, Tasman Bay (Ref. 57718).
Environment: milieu / climate zone / depth range / distribution range
Ekologi
marina bottenlevande; djupintervall ? - 91 m (Ref. 57718). Deep-water
Western Pacific: Japan and New Zealand. Southeast Pacific and Southwest Atlantic: Patagonian, Chilean and Argentine waters. Based on the geographical distance between the populations and some morphometric and meristic differences observed, assigning a subspecific name to each of these populations seems appropriate.
