Sharing the job: monogamy and parental care
In most stomatopod groups, after mating with a male, the female stomatopod lays eggs in her burrow. However, in lysiosquillids, one group of spearers, the males and females are monogamous (meaning they stay together and share a burrow). One of the goals of the Aquarius mission was to study different species of monogamous stomatopods.
The male and female live in the same burrow, but have different "jobs"the female takes care of the eggs and the male hunts for food for both of them! Note that the male in the image at right has much larger eyes and raptorial appendages.
