| Abstract | |
Hydroids are one of the most important animal groups colonizing marine macrophytes. This study presents the diversity of hydroid species in plant substrate samples taken from three points of the Sao Sebastiao Channel, southeastern Brazil. The selectivity level of each hydroid species was inferred from the number of its occurrences on each species of macrophyte. Red and brown algae, especially species belonging to the genera Galaxaura and Sargassum, respectively, presented the highest diversity index of epiphytic hydroids. The epiphytic hydroid fauna of Sao Sebastiao Channel is mostly comprised of opportunistic species, presenting low substrate selectivity. A broader cluster analysis of the epiphytic hydroid fauna reported in several studies around the world suggests that hydroids are primarily related to their geographical distribution and may be secondarily related to the lineages of macrophytes.
