Crabs used a limited repertoire of behaviours when attacking resistant prey. Crushing and rotating were the most commonly used behaviours with all prey types. Other behaviours, such as sawing, biting and poking became more important in prolonged predatory acts. Crabs were able to improve their handling efficiency; the frequency, but not the duration, of behaviours decreased with experience.
