To investigate the molecular diversity of symbiotic algae at the latitudinal limits of their distribution, the ribosomal RNA gene sequences (rDNA) of the dinoflagellate Symbiodinium in benthic Cnidaria (corals, sea anemones etc.) on Bermuda (32°N) and in the Mediterranean and NE Atlantic (35 to 53°N) were analysed. The algae in Bermudian Cnidaria were identified as Symbiodinium of Phylotypes A, B and C, as previously described for benthic Cnidaria in the Caribbean (12 to 27°N). The algae in
