Mangrove clams, known as mangrove oysters or mud oysters. Are a group of bivalve mollusks. They inhabit intertidal zones. In tropical and subtropical regions of the oceans. There are several species of mangrove clams, found in different parts of the world, and, that were probably very important to survival. During prehistoric, and the neolithic period.

They have adapted to live in the challenging and dynamic environments. During high tide, they are submerged in water. And, low tide, they are exposed to air. During this time, they burrow into muddy substrate. To avoid desiccation, and maintain moisture, using their strong foot holds.

Mangrove clams are harvested for human consumption, and they are still considered a delicacy in some cuisines. However, overharvesting can have negative impacts. Like with less food for birds, crabs and fish. And, as filter feeders, because they remove organic particles and algae from the water. It is crucial to manage their harvesting, and to positively manage the mangrove ecosystem. Even during neolithic and pre-historic times.
