Clams are not carnivores; they are primarily filter feeders. This means that they obtain their food by filtering plankton, algae, and other small particles from the water as it flows through their bodies. While some species of clams may occasionally consume small amounts of organic material, their diet mainly consists of non-animal matter. In essence, clams are more accurately described as herbivores or omnivores, depending on their specific diet, but they do not actively hunt or consume larger prey like true carnivores do.
