This type of Shrimps named lobsters are responsible for the mounds that you can observe in the mangrove area; they dig and feed on the organic matter in the mud piling up volcano shape mounds.
This in turn helps mangrove area to recycle nutrients; by paving way for air and oxygenated water to enter the otherwise oxygen deprived soil. In addition these mounds also serve as temporary accommodation for juvenile sea creatures during low tide, as they tend to gather small water pools.
