Prosthiostomidae
Prosthiostomidae is a family of rhabdocoela flatworms within the class Turbellaria. These flatworms are primarily found in marine environments and are known for their simple body structure and free-living lifestyle.
Taxonomy[edit | edit source]
The family Prosthiostomidae belongs to the order Rhabdocoela, which is characterized by its simple, unsegmented body plan and the presence of a pharynx. The family includes several genera, with Prosthiostomum being one of the most well-known.
Morphology[edit | edit source]
Members of the Prosthiostomidae family typically have a flattened, elongated body. They possess a simple digestive system with a mouth located on the ventral side. The pharynx is muscular and can be extended to capture prey. These flatworms lack specialized respiratory and circulatory systems, relying on diffusion for gas exchange and nutrient distribution.
Habitat[edit | edit source]
Prosthiostomidae species are predominantly marine and can be found in various oceanic environments, from shallow coastal waters to deeper regions. They are often associated with sandy or muddy substrates where they can burrow and search for food.
Reproduction[edit | edit source]
Prosthiostomidae flatworms are hermaphroditic, meaning each individual possesses both male and female reproductive organs. They can reproduce sexually through the exchange of sperm with another individual or asexually through fragmentation and regeneration.
