Observations on the feeding behaviour of the Antarctic GammaridEusirus perdentatusChevreux, 1912 (Crustacea: Amphipoda) in aquaria

摘要

The feeding behaviour of adultEusirus perdentatuswas observed in aquaria. These observations and the analysis of gut contents of preserved specimens demonstrate that this species is a carnivorous predator feeding on polychaetes, amphipods and other small crustaceans. Apparently the localization and capture of prey in aquaria follows a fixed pattern.
