Red Algae

Abstract

Red algae, or Rhodophyta (rhodon = rose; phyton = plant), are most commonly found along rocky stretches of seacoasts. Most of them grow in the lower part of the intertidal zone or in deeper water where they are not exposed to the full force of wave action. Red algae are found in all oceans but are more abundant in warm marine water. Although they are mostly marine, several fresh-water species are known. These usually grow in cold, swiftly-flowing streams. The red algae’s color can be used to distinguish them from most other algae.
