The survival of Nausithoe aurea Silveira & Morandini, 1997(Cnidaria, Scyphozoa, Coronatae) under extended periods of starvation
The results of quantitative and qualitative starvation experiments with Nausithoe auera polyps in natural and artificial seawater were compared. For this study, Scyphistomae growing on stony coral debris in the São Sebastião Channel (Brazil) were sampled by SCUBA divers. The data obtained reinforce...
