Trematode Life Cycle at Life

Trematode Life Cycle. The life cycle of a typical trematode begins with an egg. Their complex life cycle is dependent on different species of animals including all vertebrates and most of the invertebrates found on land, freshwater as well as marine environments.

The life cycle of digeneans is complex, but a common feature is that aquatic snails act as intermediate hosts. Structurally, trematodes are flat and elongated worms whose outer surface (tegument) contains microvilli that both protect the worm and act as a nutrient absorptive surface. Almost all flukes are hermaphrodites, with the exception of schistosomes.

Some trematode eggs hatch directly in the environment water, while others are eaten and hatched within a host, typically a mollusc. This striking polymorphism may be caused by two reasons.
