The high activity in coastal regions contributes to the abundance of coastal biota such as Matuta victor. Matuta victor is aggressive, omnivorous, and invasive, reflecting the characteristics that make it a successful invader. This crab is a supporting organism in aquatic ecosystems, playing an important role in food webs. It provides ecosystem services that enhance ecosystem productivity, including improved fishery products with economic value. This research aims to report the distribution of M. victor and compare M. victor in the West and East of the Java coastline based on COI mitochondria. Collection of specimens was carried out in Carita (n=7), Ujung Kulon (n=2), Bomo (n=3), and Muncar (n=1) by hand. The specimens were analyzed using COI mitochondria fragments. A total of 814 bp sequence data was obtained from this research. Based on genetic distance and phylogenetic analysis, specimens of M. victor from the West and East of the Java coastline had genetic similarity. This result suggests that gene flow occurs between locations. It can be concluded that the M. victor in these locations may have the same ancestor and provided distribution patterns of this species.
