|---|
| Abstrak (Bhs. Indonesia) | Fiddler crab belongs to the subphylum Crustacea, Order Decapoda, and the Family Ocypodidae. Fiddler crab are characterized by sexual dimorphism and asymmetry in one male crab claw. Therefore, this study aims to evaluate the diversity of fiddler crabs in the Segara Anakan mangrove ecosystem based on morphological characters and number of species This research purpose was conducted by survey and purposive random sampling techniques. Stations determined by the difference in vegetation and samples of fiddler crabs caught randomly (random sampling) from natural habitats in Segara Anakan, which was conducted 2 stages at four stations in the villages of Kutawaru, Tambakreja, Ujunggalang, Tritih Kulon, and Ujunggagak. Additional specimens from the crustacean collection at Museum Zoologicum Bogoriense (MZB) will also be used. The variable are the Meristic, Morphometric and General Morphological. The data obtained was analyzed descriptively. The result indicated the general morphology of fiddler crab species can be differentiated by color patterns, carapace shape, and chela variations. Meristic characters of fiddler have differences in the total number of long grooves of the dactylus, predistal triangular teeth, and tubercles on the orbital floor. Variations in morphometric characters on CL, CW & PL measurements were significantly different between individuals of 9 species (A. annulipes, A. triangularis, T. arcuata, T. bellator, T. coarctata, T. dussumieri, T. demani, T. forcipata and T. rosea) |
