MATERIALS AND METHODS

The molluscs found in the mangrove areas were compiled from various studies conducted in Indian mangrove areas. Molluscs were sampled in the mangrove areas through random collection of leaf litter and by opportunistic observations at low tide during 2010 and 2012. The molluscs from leaf litter samples were segregated by thorough examination of leaf litter under the enamel tray in the laboratory. Opportunistic observations were performed in Aghanashini, Gangavali, Kali, and Sharavathi estuaries (Figure 1), leaf litter sampling was carried out only in the Aghanashini and Sharavathi. In opportunistic observation logs, pools, stones, rocks, surface, mangrove tree trunks, branches, leaves, and roots were examined for molluscs.
