Suspension feeders are organisms that obtain their food by filtering small particles, such as plankton and detritus, from the water. They typically have specialized structures, like gills or tentacles, that help them capture these tiny food items as water flows through their bodies. Common examples of suspension feeders include clams, oysters, and sponges. These feeders play a crucial role in aquatic ecosystems by helping to maintain water clarity and quality. By consuming suspended particles, they recycle nutrients and support the food web, benefiting other organisms, including fish and marine mammals, that rely on a healthy environment for survival.
