The Holothurian is one of the echinoderms which has well known as the sea cucumber. The coastal communities in Maluku often harvest the sea cucumber for their livelihoods both for consumed and sold them. Recently, the number of sea cucumber has been decreased due to anthropogenic and environmental degradation. Therefore, the data of bio-ecology of the resources are needed to manage the resources for its sustainability. The objective of the study was to analyze the biodiversity of holothurians. Data were collected by purposive random sampling. The research was carried out from October 2017 to October 2018. The results showed that there were five species of holothurians found during this study. The abundance of holothurians ranged from 18 to 173 individuals which the highest abundance was found in March 2018 whereas the lowest abundance was found in November 2017. The diversity of species differed each month. The study indicated that there were temporal changes in diversity. The diversity index (H’) ranged from 0.733-1.346, meaning low species diversity. The evenness index showed that the abundance of each species had almost similar. So, that there were no predominance species. Nevertheless, three species have a high number or tend to be dominant later namely Bohadschia similis, Holothuria scabra and H. atra .
