Differences of ammonia metabolism in symbiotic and apo symbiotic condylactus and cassiopea spp



Differences of ammonia metabolism in symbiotic and apo symbiotic condylactus and cassiopea spp



Journal of Experimental Marine Biology and Ecology 21(1): 1-5



Patterns of the excretion of NH3 in aposymbiotic and symbiotic Condylactus and Cassiopea spp. suggest that zooxanthellae remove host-produced NH3. Greater amounts of NH3 are removed by zooxanthellae present in Cassiopea exposed to light whereas symbionts in Condylactus remove larger amounts of NH3 in animals in the dark. The rate of NH3 production by the animal is affected by light, although there are significant specific difference. The involvement of zooxanthellae in the re-cycling of N probably enchances the ecological efficiency of Condylactus and Cassiopea.
