Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum
Platyhelminthes. It infects the livers of various mammals, including humans.
Their body is dorsoventrally flattened.
They exhibit bilateral symmetry.
Also, they are triploblastic, with three germ layers.
They do not have a body cavity and are acoelomate.
Body is soft and unsegmented.
They are mostly parasitic with a few free-living
They exhibit an organ system grade of organization.
The digestive system is incomplete or absent. There is a single opening which leads to a well-developed gastro-vascular cavity. The anus is absent.
There is no true stomach structure. In a few species, the digestive system is completely absent.
Respiratory and circulatory systems are absent. Respiration generally occurs through diffusion through the general body surface.
The excretory system has protonephridia with the flame
There is primitive nervous system present.
These animals are hermaphrodites.
Sexual reproduction happens through gametic fusion.
Asexual reproduction also happens in a few species through regeneration and fission.
Fertilization is internal.
The life cycle of these organisms can be complex, especially if they are parasitic, as this may involve one or more host animals.
