In searching for images for this species, I stumbled across the Australian Government Fisheries Management Authority, which seized a cargo of 143 tonnes of this species when they apprehended an illegally-fishing vessel, the MV Taruman, in late 2005. A picture from that site:

,p>The Patagonian Toothfish (not a great common name, but somewhat cool), sold to unsuspecting (naive) consumers in North America and Europe under the restaurant name "Chilean Sea Bass"; presumably this is because the term "toothfish" doesn't sound too tasty.
The Australian vessel Oceanic Viking (behind, yellow and blue) escorts the captured MV Taruman to Tasmania, after seizure on the high seas.
I also found the wikipedia pages interesting, both for this species and the whole family Nototheniidae.
