Cephalopod fauna of South Pacific waters: new information from breeding New Zealand wandering albatrosses
International audience Cephalopods play an important ecological role in the Southern Ocean, being the main prey group of numerous top predators. However, their basic ecology and biogeography is still poorly known, particularly in the lightly sampled Pacific sector of the Southern Ocean. We collected...

International audience Cephalopods play an important ecological role in the Southern Ocean, being the main prey group of numerous top predators.
