Flatworms belong to the phylum Platyhelminthes and are known for their flat, ribbon-like bodies. They lack a true body cavity, or coelom, and their bodies are covered with a protective layer of epithelial cells. Some common traits of flatworms include:
1. Bilaterally symmetrical body plan: Flatworms have a body plan that is symmetrical along a central axis, allowing them to move efficiently in their environment.
2. Lack of a respiratory or circulatory system: Flatworms rely on simple diffusion to exchange gases and nutrients with their environment.
3. Hermaphroditic reproduction: Many flatworm species are hermaphroditic, meaning they have both male and female reproductive organs and can reproduce by exchanging sperm with another individual.
4. Regenerative abilities: Flatworms have impressive regenerative abilities, meaning they can regrow lost body parts through a process called morphallaxis.
5. Parasitic lifestyle: Many flatworm species are parasitic, living inside or on the bodies of other organisms and feeding off their host's nutrients.
6. Some flatworms, such as planarians, are free-living and can be found in freshwater environments, while others, like tapeworms, are known for parasitizing vertebrates including humans.
Overall, flatworms are a diverse group of organisms with a range of adaptations suited to their varied lifestyles.
