Mating Ritual of Cuttlefish Explained | Britannica

Flamboyant cuttlefish engage in a complex mating ritual that involves vibrant color displays and posturing in order to attract mates. The male cuttlefish will spread out their arms and alter their pigment to create a mesmerizing display, while the female will make her coloration more dull in response to a successful mate. Here the male is depositing his spermatophore to the female, who gladly accepts. This happens multiple times as long as they are not disturbed. Soon the female will lay her egg
