SECTION 03 B
Bivalves and Gastropods Species
In this section, you will find a vast collection of carefully preserved specimens of Bivalves & Gastropod species. Bivalves and gastropods are two types of molluscs that are commonly found in the museum collection. Bivalves are characterized by their hinged, two-part shells, while gastropods have a single, spiral-shaped shell or no shell.
These species are important for scientific study and education, as they have diverse ecological roles and can serve as indicators of environmental change. Museums also have collections of rare or endangered species of bivalves and gastropods, which can provide important information for conservation efforts.In addition to their scientific and educational value, bivalves and gastropods can also have cultural significance. For example, certain species have been used as food sources, currency, and even musical instruments in various cultures worldwide. Overall, bivalves and gastropods are important components of the museum collection, providing valuable information about the natural world and its history.

Bivalves
Bivalves are a type of mollusk characterized by their hinged, two-part attached to the roots of mangrove trees or other hard surfaces. These mussels are also filter feeders and play an important role in maintaining water quality in the mangrove ecosystem.
Blood cockles are another common bivalve found in Sri Lankan mangroves. They are often found buried in the mud or sand near the roots of mangrove trees. These bivalves are important food sources for local communities and are harvested for consumption.
Overall, bivalves play an important role in the functioning of Sri Lankan mangrove ecosystems by helping to maintain water quality and providing a source of food for local communities.
Gastropods
Gastropods are a diverse group of mollusks that are characterized by their single, coiled shell or absence of a shell. In Sri Lanka, mangroves are an important habitat for several species of gastropods, which play a significant role in the functioning of these ecosystems.
One of the most commonly found gastropods in Sri Lankan mangroves is the mangrove whelk (Cerithidea cingulata), which is often found in the intertidal zone of the mangrove forest. These snails are herbivores and feed on algae and detritus. They play an important role in nutrient cycling and help to maintain the health of the mangrove ecosystem.
