III. MAJOR FAUNAL GROUPS PRESENT IN THE 

 ANTARCTIC MARINE ECOSYSTEM 



The following section presents a partial list of 

 Antarctic marine fauna. Admittedly, the list is incomplete 

 and there are many other biotic components within the 

 ecosystem. For example, plankton and benthic invertebrates 

 are not included except for some Euphausiid species. Species 

 and species groups were chosen which were felt to have 

 potential commercial importance in the Southern Ocean or 

 which are known to be important in the overall ecosystem on 

 the basis of the group's large biomass. Hopefully, the list 

 includes representative species which are most critical to 

 discussions of marine ecology and the development of a 

 conservation regime for living resources of the Southern 

 Ocean. The principal sources for this information were 

 Brown et al., 1974 (whales and seals); Watson et al., 1971 

 (birds); and Everson, 1977 (fish, cephalopods, and Euphausiids)
