Distribution patterns of five zoanthid species in Okinawa Island, Japan
... I.: Palythoa tuberculosa, P. mutuki, Zoanthus sansibaricus, Z. kuroshio, and Z. gigantus. The survey was conducted using the belt transect method in 3 reef environments (moat, reef crest, and reef slope) at 10 reef sites in 2008. As a result, 2404 zoanthid colonies were observed, and Z. sansibaricus ...
