The aim of the research is to know various species of gastropods and gastropod community structure through species density, percent density, dominant species, and association of species of gastropods on seagrass ecosystem. Research with the method of quadrat transect is put perpendicular to the coastline. Gastropod species are found in the seagrass ecosystem on the Makalisung coast consist of 9 species, 7 families, and 4 ordos. Gastropod community structure on seagrass ecosystem is found with species density is highest Cymbiola nivosa as big as 0.64 (ind/m2) with highest percent density 34.04 %. Diversity of species of gastropods on four-station that H’> 1 highest in fouth station as big as H’= 1.72. The dominance of species is highest Cymbiola nivosa as big as C=0.44, where the result of research in generally dominancy C 1 di mana tertinggi stasiun 4 sebesar H’= 1,72; dominansi total tertinggi adalah spesis Cymbiola nivosa sebesar C=0,44, di mana hasil penelitian secara umum dominansi C < 0,25 adalah tergolong rendah. Asosiasi spesis gastropoda di ekosistem lamun ditemukan tiga ciri, (1) klasifikasi golongan asosiasi positif adalahCypraea tigris dan Monetaria annulus,Cypraea tigris dan Cymbiola nivosa, Strombus labiatus dan Cyclope pellucida, Strombus labiatus dan Cymbiola nivosa, Monetaria annulus dan Cerithiun nodulosum, Cymbiola nivosa dan Cerithiun nodulosum; Cerithiu nodulosum dan Angaria dephinus dan Faunus ater. Klasifikasi golongan tidak berasosiasi (2) Angaria dephinus dan asosiasi mendekati zero (0,04) yaitu Monetaria annulus dan Cymbiola nivosa. Dan klasifikasi golongan asosiasi negatif, hasil penelitian sebagian besar menunjukkan asosiasi negatif pasangan spesis gastropoda di ekosistem lamun.Kata kunci : Gastropoda, Kepadatan, Diversitas, Dominansi, Asosiasi.
