Sea urchins, soft-shelled invertebrates (Echinoderms), crucially contribute to cleaning the ocean bottom. However, sea urchins in tropical waters like Indonesia have not yet been fully disclosed. This study was conducted at Hutumuri and Rutong waters, Ambon City. This study assessed physical-chemical parameters, sea urchin species composition, classification, and community structure. Employing the Line Transect method with 5x5 m quadrants and 50m transect spacing, data analysis included density, relative density, frequency of presence, diversity, uniformity, and dominance indices. Results indicated normal temperature and salinity at both stations, supporting sea urchin life, with rocky and sandy substrates deemed suitable. A total of …
