Abstract

Molluscs are marine organisms that do not have a backbone, these organisms are associated with coral reefs. This research was conducted with the aim of describing the density and diversity of Prosobranchia snails’ species on coral reef flats. By applying the belt transect method, the results show that the density of the four Mokupa stations has a relatively high density between Tongkeina, Malalayang and Bulo. While for species diversity, Mokupa and Bulo had the highest value than Tongkeina and Malalayang. According to the results of the belt transect method, is the concluded that stations close to people’s homes have the lowest density and species diversity values, this factor is influenced by anthropogenic activities or human activities. Therefore, it is recommended that there be monitoring of snails on coral reefs, especially reef flattening in order to provide information about Prosobranchia snails.Keywords: Prosobranchia, Density, diversity, belt transects, Reef Flats

Abstract

This study aims to 1) identify the species of Nudibranchia in North Sulawesi marine waters, especially in Malalayang waters, Teep waters, Sangihe waters, Bunaken waters, Gangga waters and Lembeh straits, 2) find out species of Nudibranchia that is found in all sites, and 3) find out index community structure of Nudibranchia in all sites.  The result show that there were 11 species of Nudibranchia in Malalayang waters, 27 species in Lembeh Strait, 11 species in Teep waters, 57 species in Bunaken waters, 91 species in Bangka waters, and 20 species in Sangihe waters. Up to now, there were 139 species of Nudibranchia in North Sulawesi marine waters, where Species of Phyllidiella pustulosa, Phyllidia ocellata, Phyllidia varicose, Chromodoris annae, and Glossodoris cincta were found in all study locations. The species of Doriprismatica atromarginata was only found in the Malalayang waters.  A high Index Diversity was found in Bunaken and Bangka waters, and a middle Index Diversity was found in the waters of Lembeh Strait, Teep, and Sangihe. A stable community structure was found for all locations, while a low domination was categorized to all locations. Keywords: Nudibranchia, species, diversity, evenness, domination, and community structure.
