The aim of the present study was concentrates on different group of seaweeds like green (Ulva reticulata, Enteromorpha compressa, Cladophora glomerata, Halimeda macroloba and Halimeda tuna) brown (Dictyota dichotoma, Turbinaria ornata and Padina pavonica) and red (Gelidiella acerosa, Gracilaria crassa and Hypnea musciformis) were collected from Vedalai coastal waters, Southeast coast of India for analyzed proximate composition. The protein content was recorded maximum in G. acerosa and minimum in D. dichotoma; carbohydrate level was observed in T. ornata and minimum in P. pavonica. The lipid content was acquired higher level in H. tuna and minimum in H. macroloba.
