Watch on Soap2day. The first part of the film shows the locomotion and resting behavior, phenomena of color change, burrowing into the sand and the ejection of ink clouds. The second part shows the behavior of cuttlefish during prey acquisition. Two techniques can be distinguished here: Advancing and retracting the tentacles for fast-moving and small prey; grasping with the eight short arms for defensive and larger prey. The third part of the film shows mating and reproductive behavior. The triggering signals for intercourse with conspecifics are predominantly visual.
