Abstract

Nudibranchia are known as marine invertebrates that have uniq colors and body shapes. The research was conducted in Nudifall and Nudiretreat, Lembeh Strait, North Sulawesi. The aims of this study were 1) to identify the species of Nudibranchia in both locations, 2) to know the abundance of Nudibranchia in those locations, 3) to determine distribution patterns of nudibranchia, and to know diversity of Nudibranchia in both Nudifall and Nudiretreat. The results show that 11 species of Nudibranchia were found in both Nudifall and Nudiretreat. The species of Chromodoris annae, Chromodoris magnifica, Flabellina expotata, Goniobranchus fidelis, Halgerda batangas, and 1 unidentified species were found in Nudifall, while the species of Goniobranchus geometricus, Glossidoris cincta, Phylllidia ocelata, Phylllidia varicose, Nembrotha rutilans were found in Nudiretreat. H. batangas was found to be the highest abundance, then it was followed byC. annae, C. magnifica, G. fidelis, unidenfied species (species-1), and C. magnificain Nudifall. P. ocelatawas found to be the highest abundance, then it was followed by G. geometricus, G. cincta, P. varicose, andN. Rutilans in Nudiretreat. Nudibranchia in both locations wasidentified to have random and grouped distribution pattern. Nudibranchia was found to have the same diversity among Nudifall and Nudiretreat. Factors affecting abudance, distribution patterns, and diversity were discuss in this paper.Keywords: Nudibranchia, Distribution, Abudance, Lembeh Strait.
