Phylogenetic relationships among the Caribbean members of the Cliona Viridis complex (Porífera, Demospongiae, Hadromerida) using nuclear and mitochondrial DNA sequences

A species complex is a group of closely related species, where intraspecific variability overlaps with interspecific variation. Frequently, members of a species complex do not have complete reproductive isolation, therefore, the complex may go through extensive gene flow. In the Caribbean Sea, some...
