Cryptic speciation and the circumpolarity debate: A case study on endemic Southern Ocean octopuses using the COI barcode of life
Age, growth, and sexual maturity of two New Zealand endemic skates, Dipturus nasutus and D. innominatus
Rough and smooth skates were aged by counting growth bands on X‐rays of thick sections of vertebral centra to identify late maturing and long‐lived relative to other skates, whereas rough skate are early maturing with a moderate life span.

The extensive published and unpublished literature on the biology and ecology of Antarctic toothfish in the Ross Sea region including distribution, stock structure, reproduction, age and growth, and trophic ecology in a single document for the first time is summarised.
DIET OF THE ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) FROM THE ROSS SEA, ANTARCTICA (SUBAREA 88.1)
The diet of Antarctic toothfi sh (Dissostichus mawsoni) captured by bottom longline in the Ross Sea during the 2001 and 2002 seasons was analysed and fish were the most important prey category, in particular icefi sh and Whitson’s rattail and Channichthyidae.
Trophic Interactions and Distribution of Some Squaliforme Sharks, Including New Diet Descriptions for Deania calcea and Squalus acanthias
Multivariate analyses found the most important predictors of diet variability in S. acanthias were year, bottom temperature, longitude, and fish weight, which found some species may benefit from fisheries through an increased availability of scavenged prey.
Diet of Antarctic toothfish (Dissostichus mawsoni) from the continental slope and oceanic features of the Ross Sea region, Antarctica
Abstract The diet of Dissostichus mawsoni captured by bottom longline in the Ross Sea region was examined during 2003, 2005 and 2010. The diet of sub-adult toothfish was similar to adult toothfish,…
Diet of Two Large Sympatric Teleosts, the Ling (Genypterus blacodes) and Hake (Merluccius australis)
Although size is a central factor in determining ecological processes, similar sized ling and hake had distinctly different foraging ecology, and therefore could influence the ecosystem in different ways, and be unequally affected by ecosystem fluctuations.

The Continuous Plankton Recorder (CPR) survey is one of the most extensive biological time-series in existence and has been in operation over major regions of the North Atlantic since 1932. However,…
Different food preferences in four sympatric deep-sea Macrourid fishes
Feeding habits of the four most abundant deep-sea demersal trawl-caught macrourids on Chatham Rise, New Zealand, were examined from stomach contents and cluster analyses showed that the diets of C. aspercephalus and C. bollonsi were most distinct.
