I will post this image for now, and get back to it. These symbionts infect or are drawn into the medusa/egg before liberation from the mother colony. As far as I have seen, all medusae of a given colony are either male or female. The larva is pre-charged with it's symbionts. The order and nature of events during the infection process are of great interest.

Annotated image to demonstrate the dividing cells with two nuclei. Other cells, more visible in the image above, are near enough that perhaps they are just recently divided.
