DECAPOD INVENTORY UNVEILING SPECIES RICHNESS AN DISTRIBUTION IN THE LAMPUNG REGION, INDONESIA
Keywords:
Anomura, Brachyura, crabs, purposive sampling, richnessAbstract
Indonesia is recognized as one of the world’s centers of crab diversity, with approximately 1,400
species of Brachyura and an estimated 210–300 species of Anomura. However, the data on crab
diversity is sparse and understudy in some areas. This study aims to assess the richness and distribution
of crabs in Lampung region. Survey was conducted in Tanggamus, the West Coast of Lampung, and
East Lampung using purposive sampling approach. A total of 23 crab species from six families were
recorded from Lampung region. Tanggamus exhibited the highest species diversity compare to West
Coast and East Lampung. The member of family Xanthidae was frequently observed across all three
regions. Further studies are recommended to examine ecological drivers, climate change impacts, and
anthropogenic pressures influencing crab distribution to support effective conservation strategies.
