A study was undertaken for a period of one year between January 2011 and December 2011 from Parangipettai coastal waters (Mudasalodai and Annankoil) southeast coast of India. Present study discusses the distribution and systematic position of asteroids from these study areas. There are 8 species viz., Luidia maculate (15.6%), Astropecten indicus (54.9%), A. hemprichi (6.9%), Stellaster equestris (21.7%) and Anthenea pentagonula (0.1%), Protoreaster linki (0.2%), Pentacerasterr regulus (0.1%) and P. affinis (0.2%) was observed. 4 species viz., Luidia maculata, Astropecten indicus, A. hemprichi, Stellaster equestris are commonly available in both stations, where as P. lincki and P. regulus observed only from station II and Anthenea pentagonula is newly recorded from station I. diversity indices of Shannon (H’), Simpson (1-D), Evenness, Mergalef’s species richness and cluster analysis, MDS also derived based on the number of observed species. Species diversity, abundance, richness and evenness are higher in station I than the station II. The present study concluded that station I has higher resources of asteroids (89.1%) than station II (10.9%) and this study also provides additional information about diversity ofasteroids.
