dc.description.abstract | Crabs are macrobenthos with characters that are attached to or resting on a base or live on sediments. The role of crabs in the ecosystem includes converting nutrients and enhancing mineralization, increasing the distribution of oxygen in the soil, helping carbon life cycles, and providing natural food for various types of aquatic biota. This research was conducted in the estuary area of the Meru Betiri National Park (TNMB) Resort Bandealit. Identification results from 37 individual crabs at the Estuary Resort Bandealit Meru Betiri National Park (TNMB) obtained five species from 2 families (Portunidae and Sesarmidae). In the family Portunidae, there are three types, namely Scylla tranquebarica, Scylla paramamosain, and Scylla olivacea. Whereas in the family of Sesarmidae found two types, namely Parasesarma pictum and Parasesarma cognatum. | en_US |
