Clonorchis sinensis is a parasitic flatworm that infects the bile ducts of humans and other mammals. It can cause a liver fluke infection known as clonorchiasis, leading to symptoms such as abdominal pain, jaundice, and liver damage. It is acquired by consuming raw or undercooked freshwater fish harboring the parasite's larvae.

Undigested materials are removed through their mouth because they do not have an anus.
