Method used in collecting megabenthos data is with Bentos Belt Transect. Observation results show that the megabenthos target found in South Leato waters were seven types consisting of sea cucumber, clams, trocha snail, spiny starfish, Drupella spp., sea urchins, and blue starfish. The megabenthos target density range values obtained are 0,007 – 0,435 ind/m², and for morisita index values ranging 0 - 0,6655 id with the distribution pattern of the megabenthos target found all being unifom.
