Polysiphonia    Polysiphonia sp.



This small red seaweed is about the size of your hand  although some species are bigger.   The fourteen species can only be differentiated through microscopic examination.  They are all finely branched, bright red to dark brown in color and form dense, fluffy mats.


Polysiphonia are distributed from the Aleutian Islands in Alaska to Baja California where they occur in the mid to low intertidal as well as the shallow subtidal zones attached to rocks or other hard objects.


Amphipods and other small crustaceans can sometimes be found hiding among the branches.
