STUDI KOMUNITAS FILUM MOLLUSCA DI ZONA INTERTIDAL PANTAI SUKAERLARAN DESA KENEBIBI KECAMATAN KAKULUK MESAK KABUPATEN BELU

The area which has recently received considerable attention is the coastal region / region. This is because the coastal region / region has a diverse wealth that can be utilized by the surrounding community as a source of the main food ingredients that are rich in animal protein content. Mollusca comes from Latin "mollis" which means soft. In addition to soft body also has a shell that functions as an outer framework (Rusyana, 2011).

The average value of the relative density of mollusks ranges from 0.11% - 0.34%. Of the four roaming areas, roaming areas that have the highest relative density are range I of 0.34%. The diversity index value in all 4 home ranges is relatively low. The dominance index value indicates that the entire range (4 roaming areas) is in the low category with a range of values ​​between 0.0120 - 0, 1169.
