The pie crust crab, ''Metacarcinus novaezelandiae'' (formerly ''Cancer novaezelandiae''), is a species of crab found around New Zealand and south-eastern Australia.〔(【引用サイトリンク】title=Species Register: Crabs )〕 == Diet and foraging ==
In larval form ''Cancer novaezelandieae'' consumes mostly tiny plankton. Once fully grown though they are primarily carnivorous, hunting nocturnally and preying on a variety of organisms. Molluscs (bivalves, gastropods and cephalopods) make up approximately one third of its diet and are its main food source; followed by crustaceans (amphipods, isopods, crabs and shrimp) which make up about 20% of its diet. Other food sources include small fish, sea anemones, sea sponges and algae. ''Cancer novaezelandieae'' hunts by using its powerful chelae to catch, kill, crush and access its prey, then feeds using its mouthparts. Its claws are capable of breaking open the tough shells of molluscs allowing the crab to reach the soft mollusc body inside and feed on it. Its claws allow it to effectively kill other forms of prey such as crustaceans as well.〔Cresswell, P. (1988). ''FEEDING ECOLOGY OF THE NEW ZEALAND CANCER CRAB''.
