The thallus can be either thread-like like in Porphyra where branching arrays assemble or blade-shaped like in the genus Porphyra to which the edible nori known from sushi belong. The Rhodophyta are distributed worldwide see for example the distribution of Plocamium but they grow best in waters between 10-15 ºC.
Only two percent of these species are found in fresh water and those are only found in very fast flowing streams. Rhodophyta are predominantly marine often flourishing at greater depths than green and brown algae owing to the presence of phycoerythrin which is apparently capable of utilizing green and blue light rays which penetrate deeper in water than others for photosynthesis. Carotenoids are also found in plants and those in red algae are similar in structure and function.
They are mostly marine multicellular algae including notable seaweeds.
