The curled octopus is related to the octopus. It is named after the way it curls up its arms. A row of suction feet are found on the eight slender arms. The curled octopus uses these arms to catch its prey. Just like other cuttlefish, it can recognize objects with its excellent eyesight. It closely observes scuba divers, following every movement. As soon as it no longer trusts the situation, it rapidly disappears behind a curtain of ink.
