We mated two Larger Pacific Striped Octopuses. This video shows them interacting. During the video, you will see a small white string, which is the spermatophore released by the male. The female (who turns white during this sexual encounter), was reluctant to mate and was aggressive toward the male. The picture below shows the male’s reproductive third right arm, which has had the tip clipped off by this unwilling female! Consent really is important, if you want to keep your suckers. The last photo shows a unique unilateral color display.
We also mated the peacock mantis shrimp, (Odontodactylus scyllarus). The less colorful female solicits the sexual behavior from the male and the copulation (short though it may be!) that results is shown in the video below.
