The broad-arm Sepia or Broad-Club Sepia ( Sepia latimanus ) is the second largest species of Sepia after the giant sepia from the group of cephalopods (Cephalopoda). They have a coat up to 50 cm long and weigh up to 10 kg.

Way of life and distribution

The species is widespread and lives in coral reefs at a depth of up to 30 meters. It can be found between the Andaman Sea to the Fiji Islands and Australia . The broad-arm cuttlefish prey on small fish and shrimp . During the hunt, the diurnal animal lets tapes run over its body in a fast rhythm with the help of its chromatophores and thus seems to hypnotize its prey.

Reproduction

The mating of the broad-arm cuttlefish takes place in shallow water at a depth of up to 30 meters between January and May. The males show themselves in a strong blaze of colors. The females usually lay their well camouflaged eggs between the edge of the outer reef and the coral roof. After about 38 to 40 days, the small broad-arm cuttlefish hatch and hide under the corals.
