Description

Since the end of the ice age, members of a diverse group of polizoans became the main reef-formers in the warm waters of Polinices. The alvearians, also called hive sponges receive this name due to their ecology, in which a sessile queen generates thousands of diminutive mobile drones in charge of collecting and providing food. Skeletons of these organisms pile up to form vast expanses of reef, extended for hundreds of millions of square kilometers in the bottoms of Dillon Okeanos. These reefs are the largest and most complex ecosystem on the planet, harboring countless species of polizoans.

In the image, some stegocaudates about 3 to 4 cm swim in the shallow ocean. In front them, a genus of hive sponge.
