Cystophora is a genus of brown algae found mostly in temperate waters around Australia. Most of the southern Australian species can be immediately recognised as belonging to this genus by their characteristic zigzag branching pattern. Identification of individual species is generally more difficult and relies on the size and shape of branches, particularly terminal branches, which are specialised reproductive structures known as receptacles. Due to their local diversity and dominance in southern Australia, they are regarded by some as 'the eucalypts of the underwater world'.
