"And here we see the female warship begin the mating ritual by presenting herself to the male admiral she has chosen. Notice how she begins by flushing her facial skin. This is a sign of her health and fertility, along with the curves of her body she reveals as she presents herself to her mate. The ritual cannot be rushed however, and so the female takes slow, deliberate motions, to further entice her mate."
