Habitat selectivity of megalopae and juvenile mud crabs (Scylla serrata): implications for recruitment mechanism
Megalopae of several crab species exhibit active habitat selection when settling. These megalopae usually select structurally complex habitats which can provide refuge and food. The portunid mud crab, Scylla serrata, is commonly found within the muddy estuaries of the Indo-West Pacific after attaining a carapace width > 40 mm. Despite substantial efforts, the recruitment mechanism of juvenile m...
متن کاملHabitat creation and biodiversity maintenance in mangrove forests: teredinid bivalves as ecosystem engineers
Substantial amounts of dead wood in the intertidal zone of mature mangrove forests are tunnelled by teredinid bivalves. When the tunnels are exposed, animals are able to use tunnels as refuges. In this study, the effect of teredinid tunnelling upon mangrove forest faunal diversity was investigated. Mangrove forests exposed to long emersion times had fewer teredinid tunnels in wood and wood not ...
متن کاملNon-indigenous giant mud crab, Scylla serrata (Forskål, 1775) (Crustacea: Brachyura: Portunidae) in Malaysian coastal waters: a call for caution
Introduction of non-indigenous species into a well-established ecosystem can be detrimental, resulting in both ecological and economical damage. Two specimens of giant mud crab, Scylla serrata were found for the first time in two geographically distinct mud crab landing sites (Matang Mangrove Forest Reserve, Perak and Kota Marudu Mangrove Forest, Sabah) in Malaysia. Their identities were confir...
متن کاملThe embryonic development of orange mud crab, Scylla olivacea (Herbst, 1796) held in the captivity
This study attempts to observe and record early embryonic developments of the orange mud crab, Scylla olivacea. The period taken by the eggs to hatch was 8 days and the colour of the eggs gradually changed from yellow to brown, gray and dark gray. During the embryonic development, the developing embryos reached the blastula stage within 24 hours with a mean egg diameter of 329.91 µm ± 6.62. The...
