Abstract: In this study, the assessment of alcyonaceans was conducted in Tuticorin coast of the Gulf of Mannar during the period between 2010 and 2012 in 5 locations; Vaan, Koswari, Kariyachalli and Vilanguchalli islands and mainland Punnakayal patch reef. Average alcyonacean coral cover in Tuticorin coast was 6.76% during 2011-12 which was 5.61% during 2010-2011. Percentage cover of alcyonacean corals increased in all the study locations; Kariyachalli 12.04 to 13.96%; Vilanguchalli 8.94 to 10.23%; Koswari 1.6 to 3.69; Vaan 0.53 to 0.72; mainland Punnakayal patch reef 4.95 to 5.21% was documented. In total, 15 species from 7 genera were recorded during the study period. Though anthropogenic threats in Tuticorin coast are comparatively high, the abundance of alcyonacean corals has increased considerably showing their resilience and adaptability.
