Clam

Clams are found in the Jang Hui river, and they have been deformed due to the extreme pollution.

Anatomy
Taken from the bottom of the filthy river bed, Clams are filled with all sorts of disgusting substances including dirt, seaweed, and dead bugs. They are bivalved mollusks somewhat brown in color and have what appears to be blisters on their shells. Nevertheless, these Clams are sold as food in the village of Jang Hui.

Connection
Clams are mollusks, which are invertebrate animals whose bodies are protected by two symmetrical shells. Clams have no brain or eyes, but do have a set of kidneys, a heart, a mouth, and an anus. They feed on plankton, and their natural predators are small sharks and squid.
