The species has ecological value that is suitable for bio-indicators of the environmental condition. Since the Bay relatively isolated area, then we examined the impact of the geographical conditions on genetic diversity and connectivity of <em>Tripneustes gratilla</em> among populations in the region surrounding Cenderawasih Bay based on the mitochondrial cytochrome c-oxidase-1 gene. Results of the study showed that genetic variation of the species within the population is high; despite the genetic variation among populations was low. The data suggested that the entire population of <em>T. gratilla</em> were closed connected, homogeneous, and shared polymorphic profile. Then we assumed the gene flow occurred for a long time among populations without geographical barriers. This information is a warrant to develop an effective strategy to maintain biodiversity in the Cenderawasih Bay.</p&gt;}, number={2}, journal={HAYATI Journal of Biosciences}, author={TohaAbdul Hamid A. and Ambariyanto, Ambariyanto and Widodo, Widodo and Hakim, Luchman and SumitroSutiman B. and AmininAgustina L.
