The current trend in research area is exploring the marine organism and plants for finding out new therapeutic compound and the research is now moved towards the marine red algae. They are diverse in some extent and they belong to ancient group of marine organism. They are important ecological primary producers because they play an important role in maintaining the coral reefs by secreting calcium carbonate on their cells that provides the structural habitat for many other micro organisms. It has many biotechnological applications that make the red algae as effective anti viral agent, anti diabetic agent, anti inflammatory agent, anti microbial agent and good anti cancerous agent. We can able to create a 100% good nutritive and pure food by combining this red marine algae and spirulina an alga with good nutritive content. Thus unique and unpredictable features of the marine red algae can be studied only if its genetic nature is fully revealed.
