The marine environment represents approximately half of the global biodiversity and is an enormous resource for new compounds. Seaweeds are also known as marine macro algae and they are a habitat of both marine and brackish water environment. It is a very versatile product widely used for food in direct human consumption and also an ingredient for the global food and cosmetic industries and is used as fertilizer and as an animal feed additive. Total annual value of production is estimated at almost US$ 6 billion of which food products for human consumption represent US$ 5 billion. Hence a preliminary survey on the marine algal distribution along the Elathur backwaters and Kappad beach, Calicut, Kerala coast was undertaken during Jan – Feb 2015 and the list of algal species collected during the survey from the intertidal and subtidal region upto 1.5 m depth is highlighted in this paper.
