Sargassum

Distribution:       

Found throughout Australian waters, Sargassum grows on subtidal reefs and in rock pools. Sargassum has a distinctive stem-like structure with leaf-like branches and can generally be identified by the small bubble-like floats. However, due to an annual growth cycle, reproduction and decay, they won’t always have all these identifying features as they often die off around summer. Sargassum is a Spanish term for ‘floating seaweed’ – as the small bubble-like floats allow this seaweed to be suspended in the water column.
