Like all cephalopods, the curled octopus is an active predator (4). It usually feeds on crustaceans, molluscs and other invertebrates as well as fish (4). When feeding on crabs, the curled octopus immobilises its prey by puncturing its eye and injecting toxins into the body of the crab. The digestive enzymes contained in the saliva of the octopus break down the attachments within the crab's body, allowing the carapace to be easily removed (4).
