Many flatworms can detect changes in the amount of light in their environment using groups of cells called photoreceptors. These cells are sensitive to light and help the flatworms navigate and respond to their surroundings based on light levels.
Free-living flatworms are flatworms that live independently in their environment, rather than parasitizing another organism. They are typically found in freshwater or marine habitats and feed on microorganisms, small invertebrates, and organic matter. Examples include planarians and marine flatworms.
If you understand the evolutionary relationships of an organism, you can easily look at it's ancestors and those following it to try and classify the animal. If you were trying to classify as specific type of Jellyfish (Cnidarian), you could look at the sponges (Profiera) before it, and flatworms (Platyhelminthes) after it, and see that sponges are much less complex, but flatworms are much more so. Therefor, you can easily see what class they fall into, and where in the evolutionary time scale. Hope that helps!
Some flatworms can be harmful to humans as they can cause diseases like schistosomiasis. However, not all flatworms are harmful, and some are actually beneficial by controlling pest populations in the environment.
facts about flatworms
Flatworms require muscle cells for movement, nerve cells for detecting stimuli, and epithelial cells for sensory integration and coordination of responses. These three cell types work together to allow flatworms to respond to their environment and move about.
Yes flatworms are invertebrates
Flatworms are in the Platyhelminthesphylum.
The scientific name for flatworms is Platyhelminthes.
