Cephalopod beak guide for the Southern Ocean: An update on taxonomy (revised edition)
Cephalopods play an important role in the Antarctic ecosystem, being consumed by a wide range of predators such as whales, fish, seals, albatrosses and penguins. To understand predator-prey interactions between top predators and cephalopods, effort has been put into the development of methods to det...
