However, the existence of Starfish in each region is increasingly experiencing damage due to pollution and human activities. The type of research used is comparative descriptive research. Data collection techniques are in the form of direct observation and documentation. Based on the research results, it was found that there were five types of Starfish found in the waters of Awang Beach, Central Lombok Regency, including: Protoreaster nodus, Linckia leavigata, Archaster typhicus, Culcita novaeguineae, and Henricia leviuscula. Sampling was carried out at three station points, namely station I, station II and station III, using the quadrant transect method.
