What is the coelom of liver fluke?

Answer 1

The coelom of liver flukes, which are parasitic flatworms belonging to the class Trematoda, is often considered to be absent or greatly reduced. Instead of a true coelom, liver flukes possess a solid body structure filled with parenchyma, which is a form of connective tissue. This body plan reflects their adaptations to a parasitic lifestyle, where they rely on their host for many functions that other organisms might perform independently within a coelomic cavity. Thus, liver flukes exemplify acoelomate organisms, lacking a true body cavity.
