Sponge

Sponges cling to the rocky and sandy surfaces of Orbis's Ocean floor, drawing water through their porous bodies to capture microscopic food particles. As filter feeders, they require neither movement nor aggression — they anchor in place and let the currents do the work. A sponge is entirely harmless to any player passing by and yields no loot when examined. They're easy to overlook among coral and shell clusters, but their presence signals healthy reef conditions and contributes quietly to the visual richness of the underwater world players can explore.
