Newly distribution record of four marine crabs (Decapoda: Brachyura) collected from Seribu Island-Jakarta, Indonesia

Abstract

Brachyuran is an important biotic component in marine ecosystems, and is known as a keystone species. Information about brachyuran species in Indonesia, in this case from Seribu Islands-Jakarta, is still limited, especially for the non-economic crabs. Based on the manual sampling, it was found that there are four crabs that have not been reported from the Islands, i.e. Ozius guttatus, Carpilius maculatus, Gelasimus hesperiae, and Etisus laevimanus. In term of ecological point of view, the Islands are influenced by the Jakarta Bay as food provider for supporting the live of brachyuran crab. Crab database is necessary to increase the utilization of crabs in the future, e.g. as antibacterial activity and the sources of chitin and chitosan.
