The brown algal genus Sargassum which represents 929 species names of which 335 are currently accepted taxonomically, are the most abundant plants in various major marine geographical regions from Indo-Pacific to the Atlantic Oceans, covering temperate, sub-tropical and tropical regions of the world oceans[1,2]. The giant multicellular species that comprise "kelp forests" in temperate marine waters belong to this group. [citation needed], Based on the following works of Ruggiero et al.
