This investigation was carried out in August 2021 at depths of 3 and 7 meters in Ubik, Air Baun, Kikuba, and Sawang Pari points adopting a survey method. The Line Intercept Transect observation method was analyzed to evaluate the diversity of coral reefs (55 m long). There are 45 species, which belong to 25 genera and 10 families. Kaana's coral cover falls bad to moderate (13.5 to 30.75 percent), with an average of 21.60 percent.
