Can mandible morphology help predict feeding habits in Antarctic amphipods?
peer reviewed In Antarctica, amphipods form a highly diverse group, occupy many different ecological niches and hold an important place in food webs. Here, we aimed to test whether differences in Antarctic amphipod feeding habits were reflected in their mandible morphology, and if mouthpart speciali...
