Abstract

Sampadi Island is one of the protected islands for conservation purposes in Sarawak. It consists of seagrass areas that provide food for herbivores and important as a habitat and nursery ground for aquatic organisms including crustacean, crab. A study was carried out to determine the crabs species found based on the morphology structure and the feeding habit of crabs at Sampadi Island. There are 10 species of crabs found at the Sampadi Island which is represented by 5 families of crab including Portunidae, Xanthidae, Pilumnidae, Ocypodidae and Porcellanidae. The species identified are Thalamita sp 1, Thalamita sp 2, Thalamita sp 3, Portunus sp, Pilumnus sp, Scopimera sp, Uca sp, Petrolisthes sp and 2 species from family Xanthidae. There is morphological variation in each species which made it possible to differentiate the morphology of each species. The crabs of Sampadi Island are omnivores that mostly feed on mollusks, plant materials, other crustacean and polychaete.
