Description Sea cucumbers is a group of marine invertebrates belonging to class  holothuroidea. At this time, the hunting for sea cucumber is not just targetted on the expensive species, but also the cheap one. The exploitation pressure has caused population decline which  can cause changes in their community structure. This research was aimed to understand the types of sea cucumber, analyze the structure of the community sea cucumber which includes the density of individuals, diversity index, the dominance index, interspecific  and the dispersion pattern. Sample collection was done at night at the lowest tide in December, 2013. Based on the research activities in the coastal areas of Ondong, west Siau district, Siau-Tagulandang-Biaro regency, 7 species of holothuroidea were found : Holothuria atra, Holothuria leucospilota, Actinopyga echinites, Actinopyga lecanora, Bohadschia argus, Bohadschia marmorata and bohadschia vitiensis, respectively with mean individual density of 0.797 ind/m2, diversity index (H’ = 1.718), equity index or harmony (e = 0. 883), dominance index (C = 0.218), interspecific association between 7 species forming 5 pairs of positive associations and 16 pairs of negative association andrandomdistribution.
