Growing in size, they have fused their 8 feeding tentacles into 4 and they have developed to use them to also photosynthesize. They have also developed a tolerance for lowered salinity and expanded into the Ovi Swamp and river. The reproductive methods of the Ambrelabra have changed significantly. While they have retained the fragmentation and budding processes as juveniles, as adults they have developed more complex sexual reproduction. Adult Ambrelabra will produce male and female gametes. Female gametes are released near the base of the Ambrelabra and will crawl along the substrate until they reach a suitable location to develop into a rooted juvenile. This rooted juvenile can only produce and release sexless juveniles until sexual fusion occurs. This sexual fusion occurs when a male gamete or a sexless juvenile fuses with the rooted female. When sexual fusion occurs, the Ambrelabra becomes a sexually mature adult and will switch to producing both male and female gametes. The sexless juveniles will be free swimming until either undergoing sexual fusion or becoming rooted.
