摘要：
A towed benthic camera system captured images of a ca. 66-cm-long Antarctic toothfish partially under a boulder at 76degrees30'S, 174degrees59'E (depth 454 m) in the southern Ross Sea. This is noteworthy because, excluding McMurdo Sound, there are only two published records for this species in the Ross Sea and none in an offshore locality. Adult Dissostichus mawsoni are neutrally buoyant and live and feed in the lower reaches of the water column. Benthic perching is unexpected, suggesting that this subadult is not neutrally buoyant.
